Travel Website design with integrated booking engine

This is a small project, which only involves website design around a back end booking system already in place. As far as I know, this will require XML knowledge in order to integrate it. Specifics: A website that needs to be fully designed and have a booking engine integrated into it from a 3rd party which handles online reservations for travel, flight, car rental etc. This is a travel booking website, similar to the likes of expedia, travelocity etc. We are looking for professional work in order to keep with the standard of most websites out there in terms of design, usability, and functionality. In all: 1)Website needs to be designed from the ground up, with the integrated booking engine backend from a 3rd party. The site must seem to stand independently. Using link masking is a must. 2) SEO optimized for travel 3) Logo design with a moto which we will provide. 4) Adequate revisions until we are satisfied with the project. 5) Professional work We are working of a very strict budget. If your rate is most competitive with the quality of your work, we will award you the project, after reviewing relevant portfolios of sites you have completed. Please provide us with travel websites only, as well as information on the average duration for project completion.
