Don't know anyone who could do it for you, but if you look around at some of the welding/fab shops or auto customizing places, and ask around. Either way, you'll likely have to fork out some capital to have it done!!
If I were to charge someone to do what I did to my car, it would be in the 3 figure range!! Remember, you will have to pull out the carpetting, all the rubber undercoating etc.....it's a lot of work....not difficult, but very time consuming.
