What will give you better ROI? Sending a larger list one piece of direct mail, or sending a smaller list the same piece multiple times?

Hello! Aside from the typical website platforms, I would recommend using Twitter's hashtags and user handles. Try following and using the ones that your potential prospect or otherwise ideal partners would be following and start sharing about your work, your progress, and outreach for a potential partner. If possible try to be local when doing so. But obviously, some to use include Startups.co, Basecamp, Inc 500, yesPHX, BetaBulls, MPV, Lean Startup, Lean Methodologies, TechCrunch, etc.

Back when I started LinkedIn wasn't as huge as it is now. I wish it was. I didn't have a large network and those networking sessions NEVER brought me any clients. I used to go to all sorts of them hoping to get clients. There were a couple of nibbles here and there, but never anything serious. The only thing that helped was reaching out DIRECTLY to people in my target market. That meant cold calls and cold emails. I'd sell myself while thinking about their needs. Once I got a few bites I'd build good rapport by keeping in touch, asking questions, repeating back what they were saying so that they knew I was on the same page and kept my promises. If I said I'd call them back next Tuesday at 2:15 I'd do so. Eventually I built trust with them without having a network, or an insane amount of experience. Oh and the most important thing about consulting is to LISTEN. When those first clients notice that you're truly listening and you're not selling the cookie cutter solutions everyone else is trying to sell them that's when you got them hooked. You start to understand their problems, fears, and see through their eyes and not just yours. A network will help, but in the beginning just good 'ol salesmanship will get the ball rolling.

Your best bet to get traction quickly in USA is to advertise on mobile ad networks. You may need to advertise on CPM/CPC basis instead of CPI if you have a paid app so make sure you understand your user lifetime value and watch conversion rates closely so you don't overspend. That said, depending on what your niche/vertical is, there are many other ways to market non-gaming apps.

You've answered your own question. Reach out to your prospects with the question, such as "How would you...". Ask what people want then give it to them if you can with integrity and thoughtfulness.

I don't even know how to answer this. Do you know what the difference between McDonalds and the local burger joint that is filing for bankruptcy is? It's marketing. McDonalds is worth billions of dollars not because of the quality of their food, but because of their marketing. Marketing is not an expense. A janitor is an expense. Your computer is an expense. Marketing is an INVESTMENT. Would you shop around for the cheapest heart surgeon? Of course not. Because you would likely end up dead. Why, then, do you shop around for a marketing expert? Are you ok with your company going bankrupt? Is that worth the small savings to you? No. Of course not. Hire someone who is good at marketing. Hire someone who knows what they are doing. Buy yourself a Lamborghini with your profit the first quarter. Get a beach house in hawaii. Grab a yacht. Or, try to find your business the cheapest heart surgeon you can and then spend the next five years wondering why such a solid business idea failed in the first 6 months. I'm passionate about this exact topic because all those statistics you read about "70% of businesses failing in two years" are solely because of horrible marketing.
