179814 alibabacom plus rentcom mix

Hi, I'm looking for something very similar to [login to view URL], only adopted not for appartments, but building materials. The search engine should be very similar to [login to view URL], but easiness of usage,look and feel should be from rent.com. Sellers, after registering - upload their excel-price files{all files from diff sellers comes in in diff layouts - the programm needed to bring them all to one look for search engine}, add up resumes, contact info, logos. Buyers, will be going trough the same procedure as they do on rent.com. Every seller, watched by this buyer is stored([login to view URL])After that we start automatic e-mail campaign, using all the info we have stored for this buyer(all of the e-mails will have the REBATE promotion - for pointing out who they bought from and giving the amount of purchase).After that this info automaticaly placed and redflaged at sellers account. admin panel should consist of today tasks for managers(such as "new sellers to approve","info from buyers regarding purchase" and others) and managers tools. I'm looking for someone with previous experience with similar projects to bring new ideas.
