I have $400 to start an online product/service/business. Where do I start?

What your trying is one approach to finding investors. Here's another that in my experience is far more effective. I'd tap your network, and it's probably actually a lot bigger than you think! Linkedin is the perfect tool for this. Look for people you're connected to, that you trust, and that are suited to helping your business (ideally in your industry, or experienced in fundraising, etc) and that have a good network themselves (ideally they're connected to some investors you're interested in, but not required). Reach out to them, and let them know you're starting a venture, and are looking for their advice, and would love to treat them to a 30 min coffee meeting. People love to hear that others think they're awesome and they love to give advice which makes them feel awesome, and this is someone you know, so chances are they'll accept. Send this request to everyone relevant in your network. At the meeting, tell them about your venture, give them your pitch, hear their comments and heed their feedback, and ask them for 3 people in their network that would be great people to talk to. Get intros to those people, and repeat. If you do this diligently and listen well, your network will expand extremely quickly, and you'll be able to get introduced to literally anyone you want. This is how our founding team at Tachyus acquired our first customer within 1 month of starting, and having no experience or direct connections in our industry. I'm always down to chat in more detail if you're interested. Best of luck!

They met a need for lots of people. Their values lead to long term success, but their short term growth was due to meeting a need in the marketplace and doing really well.

Kudos to you for seeing the value in great copy. I love that you mentioned 37signals, which is an organization that's made copywriting part of almost everyone's jobs (or so they've shared on their blog). MailChimp and Zendesk are two others that people often point to re: great copy that builds a brand and differentiates; Groupon is another awesome example of really, really tonal copy that people actually read (which is more than half the battle). MailChimp has in-house copywriters, including Kate Kiefer (https://twitter.com/katekiefer), and so does Groupon. I'm not sure who writes for Dropbox or Zendesk, though searching companies on LinkedIn can often reveal little-known in-house geniuses. The startups you mention have a certain style and tone that I have to say is different from what you'll normally get with a "direct response" copywriter, though by all means check out the link David Berman submitted to you because you never know. I recommend that, to achieve the slightly funky, funny-ish copy you're looking for, you seek out a conversion-focused copywriter with a creative and UX background. You need someone who's totally at ease adopting a new voice / tone and using it appropriately across your site and in your emails; less experienced copywriters might be heavy-handed with the tone, which often gets in the way of the user experience (e.g., button copy that's tonal can lead to confusion). Be careful, of course, not to push your writer to be exceptionally creative -- because a little touch of tone goes a loooong way for busy, scanning eyes. Here are some great freelance copywriters you could consider: http://copyhackers.com/freelance-copywriters-for-hire/ The link to Neville's Kopywriting peeps is also great. Before hiring, ask to see a portfolio or get a) links to websites they've written and b) a zip of emails they've written; if a writer is accepting clients, they'll usually showcase their work on their website. Check out their blog and tweets to see if their voice comes through in their own writing. Don't hire bloggers or content creators for a job a copywriter should do. Don't hire print copywriters for web work unless they do both. And when you find a great copywriter, trust them... and don't let them go - because 10 bucks says, they're in demand or about to be.

I think as a first-time entrepreneur who is non-technical, you should focus 100% of your energy on your clothing business with your buddy. There is far less required to make a clothing business a success than a startup run by a non-technical founder. I don't mean to trivialize the challenges of running an apparel company (there are many) but comparatively, there is a greater chance of you having success with the apparel business than a startup. But you *reduce* your chances of success by diluting your focus with other ideas. Happy to talk to you in a call about starting off on the right foot with a cofounder.
