Dallas Area Welder

Hi there fellow builders! I'm going to need some modifications made to my trailer frame sometime in January. Making it wider, adding fender, and side runners (Ex, http://s773.photobucket.com/user/switaw ... 1.jpg.html).
Can anyone recommend a local welder or business that won't charge me an arm and a few legs?
