What gage steel to patch frame and need to hire welder

[Lisa and Mark <bugtop@comcast.net>]

Hi all,
I have a few rust holes at the front lower section of my BJ8 frame.  I 
want to patch the area and was wondering what is the preferred gage of 
steel to make a patch?
Also, I am in the Bay Area peninsula, (Mountain View) and was hoping 
someone would have a reference to a welder who can make house calls.  I 
have my whole front suspension apart and  cant move the car.  If you 
prefer, you can contact me with welder references at
bugtop@comcast.net.
Thanks all!    Mark Buggy
