I'm looking to have a business webpage made.
The business is somewhat similar to priceline, wherein, the client goes to the site, names their price for a service, and is then matched up with a provider for the service.

I'm not the most tech savy guy out there, so I'll obviously need assistance in creating the above.
For the purposes of the website, what type of professionals do I need?

- Web Designer
- Web Graphic Artist
- Webpage developer/programmer?
