Drupal business directoy

I'm looking for a Drupal developer who can help me get started and build my new site in [login to view URL] site content will be business directory and I would like the site to have similar search functionality as [login to view URL] or avvo.com. - search page -- location -- name -- category -- sub category - search results - refine your search - sort - business profile page -- name, address, company info -- rate and review business - edit business profile I would like existing business to be able to log in and edit their business listing - add new business profile I'm a PHP developer myself but I never worked in Drupal yet and I don't feel like reinventing the wheel by building the site from scratch. I'm not looking for finished project but rather for someone to build the core functionality listed above.
