Rails Development Project

This project will require two types of interactions: one for restaurants and one for restaurant goers. Restaurants will be able to sign up with Facebook or Twitter, and then post reservations they wish to sell to the site. After the reservation has been posted, restaurants can link their PayPal accounts to their accounts on my site so they can receive the funding, we notify them that we take 15% of each reservation sold, and then the restaurant receives a notification with the details of the reservation post. On future logins, the restaurant can login and post new reservations for sale. People looking to buy reservations come to the site, can search for a restaurant or go through a listing of the reservations being sold on the home page or a separate page, enter their email address if they are interested in purchasing a reservation, and then buy the reservation with PayPal (85% goes to the restaurant's account and 15% goes to my PayPal account). Then an email is sent to the restaurant notifying them that the reservation has been bought and an email is sent to the reservation buyer letting them know they just show the email to get in at the reserved time. This is all detailed in the work flow. I'm looking for a Rails developer who has designed simple interfaces that are easy to use.
