I think introverts or those with social anxiety disorders have more to gain with Rejection Therapy than highly social extroverted people (like yourself).
What I suggest is getting a Facebook fanpage up, and corral all your friends. You could get a following for your site that will revisit it again and again.
"This just means you're constantly asking people to give you things."
Not necessarily. How often have we seen people not offer assistance to a needy stranger? Or pay someone a compliment? Or say hello to a complete stranger? We don't because we might not get a response we expect.
Rejection attempts should always be a win/win, or at the very least completely harmless, and Jason demonstrated that.
I tried something similar. I designed websites for five local restaurants, all at the same time, then SEO'd them into top positions on Google. Then I went door to door to each restaurant and showed them the websites, live online.
The restaurant owners wouldn't need to do anything. They could assume possession of the website that very day (I would only need to change some pictures and change the website name from "Your Family Restaurant" to their name).
Guess what... I only moved one, and even that one was a special deal. I couldn't even rent the other websites out for a small monthly fee.
I figure it wasn't a price point as much as they just didn't see the value in having a website. If they did, they'd already have a website.
Lesson: Let people come to you. Let them have the need first.
BTW: Every now and then, late at night, I'll get a takeout order for lettuce wraps and fried rice (sigh).
