Greetings,
The provided short description has revealed the major aspects of your project.
The accompanying bid, along with the time estimation is only a tentative one, as the provided short description has revealed us only the general aspects of your requirements.
We would like to draw your attention to one of our successful projects that has been finished earlier, showing certain points in common with your purposes:
* Accommodations Network - A multilanguage accommodation network, similar to Airbnb, allowing it's users to post their properties, availability dates, place/accept reservations, rate their experience and use private messaging to communicate with other users. Has quite a large set of social features, uses PayPal payment gateway and PayPal MassPay.
You can find this and many other websites in our portfolio at: http://www.freelancer.com/u/devexpertsteam.html
We would be able to offer you a bespoke and turnkey system that will become fully usable after you have entered your data and will remain in your control after the launch.
Life-time Bug-free warranty is a part of our standard service.
We would be glad to answer your questions and provide required assistance.
Best Regards,
Andrei
