new website for Travel agency

we are looking to re-do our current website, ([login to view URL]) the contents of the site will remain, the same, its just the look of the website will need changing, to give it a more professional look, we would like to integrate our internet booking engine in a small box in the home page. currently the internet engine is provided by amadeus through an external link, this CANNOT be changed, as amadeus will not provide api servises, and there web services are too costly to obtain. therefore we must link the search engine to input data into this link and obtain its results from this link. the functionality of the link will remain the same. its just the way it is presented to the customer will change.
