Online Travel Agent Website design, API integration, XML etc

1. We want to have a B2C Online Travel Agency website designed which will have an API integration with a third party travel wholesaler. 2. The same B2C website will be linked with our own B2B portal by using a tab, link or any content. 3. Also need to have a international standard branding, logo design, business card design & etc.... Detail Summery:- The basic idea is, there should be a B2C portal/website for online travel agency & this website will have an API integration with our partnered wholesaler, who will provide us the inventory & this will automatically travel from the wholesaler's site to our B2C site through API integration, XML integration & other necessary technologies. Now when a customer visits our B2C site they can view the rate, inventories & other details of the hotels supplied by the wholesaler, but there should be a small button or link under few of the hotel's rate (as per our wish) & when a customer click on that button or link he/she will be redirected to our own B2B site fro more special rate, but to avail the service he/she has to become a member of us & their would be certain charges to become a member, so from that B2B site a customer can pay directly to us & become a member to avail the special service offered by us. This B2B site will not be accessible without the membership & an unique user credentials.
