battery trey/rear valance rust, how to deal?

[LittleBimmer]

im interested in fixing this myself, i know nothing about body work but i see some people on here make this stuff look easy
how can i go about this?
i have taken any paint off the infected areas yes but
this is what is visible


this is a picture of i think a tow hook.. i could be wrong its on the driver side of the car.
on the right of the picture is the muffler


thanks!
i might have a friend that can let me barrow their mig welder.

strip all surronding paint/rust
1) Cut and weld
2)grind
3)body filler/sand
4) finishing filler/sand
5) prime

how would i go about fabricating the new metal?
what would be the minimum welder i can use?

since i know nothing about welding and my friend is being sketchy about their mig welder..
would this be a good investment for this repair?

see latest post in my thread. You can get a little part fabricated if you cut it out and bring it into a good shop.

I can't really tell what you need from the pictures but I have California parts car we are cutting apart this weekend and if this is a piece that I can cut out we can figure out a fair price for it. I have cut out lower fender pieces and shipped them back east for body cancer repair. PM me if you are interested and we can figure out if I can help.

Cheers,

and about one square inch of the battery trey corner.
how much would you need to cut a decent section of these out for me?
