Help with rust repair

['65 chevy lover]

I have approached two different local company's (Hot Rod Shops), which will remain nameless, to fix the rusted out places. One guy ( in Northlake, TX )said he was going to come by and look at it and give me an estimate but, never came by even after talking with him two or three times. Another local place (Keller, TX I believe) promised me he(after sending pics) would get back with me today but hasn't called me either. What the heck is the deal with places...do they not want the work? I'm just about to the point where I'm ready to throw in the towel! I'm working so much that it's hard for me to work on this thing, plus, I don't know enough about doing this kind of stuff to really feel comfortable trying to do it, that's why is going to pay a shop to fix the rust. I just want to get the truck running. Can anyone recommend a reliable shop to do this? I'm posting the pics I have. Although you really cant see, pretty sure inner and outer rockers on both sides need replacing and, some of the floor. Also, there is a place right under the passenger side of the windshield that has a bubble(kinda hard to see). Thanks for help!
