Where do I find entry-level interview-based business / marketing podcasts that I could promote my new book on?

I think differently about this, because of two reasons: 1) I've always (and only) been involved in bootstrapped startups; and 2) I've been lucky that those startups grew organically and fast (enough) which minimized our need on marketing spend. Instead of deciding on a specific budget for this, I would instead look at your current priorities (in terms of budgeting and re-investment into your team): 1. Build a great team. 2. Build a great product. 3. Craft incredible customer experiences. 4. Spend money on marketing. If you've already hit all 3 top priorities and you can't reinvest any further into those, then you should start spending money on marketing. If you don't have revenues today and you are hoping to generate revenues through marketing spend, you're on slippery slope (says the bootstrapper). Whilst not wrong, this is tricky and you'd need to take a realistic look at your customer acquisition cost (CAC) and how much you can invest into acquiring new customers.

Cash money should be treated separately than sweat equity. There are practical reasons for this namely that sweat equity should always be granted in conjunction with a vesting agreement (standard in tech is 4 year but in other sectors, 3 is often the standard) but that cash money should not be subjected to vesting. Typically, if you're at the idea stage, the valuation of the actual cash going in (again for software) is anywhere between $300,000 and $1m (pre-money). If you're operating in any other type of industry, valuations would be much lower at the earliest stage. The best way to calculate sweat equity (in my experience) is to use this calculator as a guide: http://foundrs.com/. If you message me privately (via Clarity) with some more info on what the business is, I can tell you whether I would be helpful to you in a call.

Budget is definitely important for a successful business, but it is not everything! As a young entrepreneur, I started a similar business earlier in my career selling eyeglasses on eBay. I created an eBay store, worked on advertising, and was fortunate with my results. I would love to speak with you about starting a website and marketing effectively to consumers with a very small budget. The biggest recommendation I can provide is to test different services at a low budget to see what works. Rather than spending thousands of dollars on a marketing agency, there are many services that can help your iPhone case business in marketing effectively. Feel free to reach out to me!

I have to ask why you would start an agency in an area you don't have much experience in. Perhaps you'd be better off getting at least a little experience first?

After founding one company on my own, and co-founding several others with teams, I've written and spoken extensively on this topic - it's an under-recognized risk and challenge of entrepreneurship. You can read one of my more popular articles at http://lp.co/perspective, but I'll summarize it here... Entrepreneurship can be a very lonely endeavor. Even when you have others on your team, no one else is in quite the same "boat" that you are. Looking to other entrepreneurs for support can be deceptive. Most entrepreneurs are always "on" - showing only the best side of their business - and it's easy to understand why. As an entrepreneur, you're constantly selling yourself and your company to potential customers, employees, and investors. As a result, you compare yourself with others who are only showing their best side (and only sharing the good news), while you know that your own pursuit is a daily struggle. Raising money (if you are going that route) is an exercise in perpetual rejection. It's a real test of your self confidence to be told over and over why your idea won't work and isn't worth an investment. If you're not raising money, you may deal with this same challenge when trying to find your initial customers or employees. I've found three primary ways to counteract these forces and stabilize my own perspective: 1. Find some peer entrepreneurs with whom you can build some truly deep and transparent relationships, where the masks come off. Share your insecurities and vulnerabilities with them, and allow them to do the same. 2. Find mentors, advisors, and coaches who have experienced the same ups-and-downs you are facing. Listen to their stories, soak up their wisdom, and most of all, realize and remind yourself that they survived it, and so can you. 3. Recalibrate your perspective by taking time off to help others who are less fortunate than you are. Volunteer with an organization that supports a cause that you care about. The side effect of focusing on others is that you will be reminded that the challenges you are facing are not the worst problems in the world.
