Advice on welding small floor patch (SF Bay Area)

[Luke87gt]

Hi guys, my 69 has solid floors.

However, right over the transmission (just in front of the bench), the floor has 3” x 3” hole that needs to be patched.

I’m looking for someone local that has experience welding sheet metal and can make a house call.

The hole is very accessible with the bench out (I’ll have it out).

Does anyone have a recommendation that I can pursue? Thank you!
