Need Online dentist Portal in PHP

Project Description:
Hello Mates,

I am currently searching a company of Group of experts who could provide us assistance with permanent support over our new project.

Here are the requirements for which we are searching appropriate person with appropriate costing.

The concept is to develop a website which will provide listing of all desist over a particular area. The entire dentists who are register will have their listing with reviews and ratings. Any free user will have access to drop a review to any of the dentist which will be approved via Admin and then it will come live. We will join dentist from admin panel as well as we will also provide direct registration.

We will therefore offer them sub-domain under our main domain over which they will be able to develop their own website.
An dentist will join over the website by finding it in Google. In this way he will need to make online payment and purchase monthly or yearly subscription (this will include hosting charges which will be shared hosting). As soon as he will complete payment he will be provided a mail with confirmation of this membership. He will also be able to search his sub-domain name (we will provide this option) while completing the membership process. (Domain name costing will added to plan).

Over master website each dentist will be listed and get ranking on basis of review the more review will make him in tip listing.

I hope you all will get an Idea of website I will discuss more with the selected candidate. I will need a SRS and complete proposal with your portfolio.

I understand it is big project but Pricing should be reasonable as in involve you completely with ongoing support and recurring.

Let me know your thoughts.

The master website will function same to same as http://doctoroogle.com/.
Listing, dentist profiles, review system will all be same.

Hope to see your bids. I need to choose appropriate person very soon so please hurry up.

Thanks
