Hey,
My friends and I just started this service and we would love to hear what HN thinks about it.
We promise to deliver good quality in any design task customers submit and at the same time we promise to deliver it under 24 hours.

The landing page isn't particularly attractive, easy to read, or clear. It might be worth hiring one of the designers you have a relationship with to have it professionally done. Everything on the "how does it work" page should probably be on the front page, which doesn't do a good job of conveying what you're offering or what a buyer can expect for that $99.
The headline doesn't really capture what you're doing either -- "we design so you don't have to" might describe the web design profession, but not you as a middleman offering unlimited design work on retainer.
