Recommend Body Work shop

[zdpz]

I need recommendations for body shops that wont rip me off and can help find an affordable solution to fix this issue (which is coming out of my pocket, for my carelessness, no insurance involved!). So far I have received quotes up to $25000 $2,500!!! They are at Gyro Mazda and Toronto Mazda.

The bottom portion of my doors near the rocker panel, and the rocker panel itself are dented as they were struck against a curb/rock causing it to bulge inwards.

I dont have pictures, but here is what the damage looks like:










I was thinking about just repairing it myself, as I have fixed the paint already and rust proofed it till I get a permanent fix. And losing my car for a week will be another expense. HElp and Advice please!!!
