Finish incomplete ASP.NET 2.0 web site.

We have a partially-completed ASP.NET 2.0 web site that access SQL Server for content and uses Master pages.? The site looks different in Firefox, Safari and MS IE 8 compared to 7.? We need to fix the master page to look the same on all browsers.? The menus, especially, look different.? We have a large number of Mac customers. We also need to finish coding up a downloads routine that will capture the downloader’s information and save into an existing database structure. The site we’re updating was conceived a couple of years ago; we need to update the look and feel of the site to 2010 standards. There is a new company logo for the master page which will be supplied to the winning bidder to complete the page. The web site is at <[login to view URL]> if you wish to review. **This site does not require e-commerce functions, and most of the download code is in place.? We're looking at very simple pages for the most part.? Our news feed work is completed.**
