Best way to patch fiberglass?
Been googling a fair amount and trying to figure out the best approach to patching up my problem. It looks like the previous owner might have backed into a cement pole or something, and punched a hole...

Yes, you can do this yourself.
Look at my roof repair in the link below. It was a little bigger than what you've got, and on a curved surface. The link has pictures and some limited instructions.
If you've never worked with fiberglass before, try to find someone to help you with the rosin mixing and the first layers. I'd try to put at least 3 layers of fiberglass on the back side with 3 more on the outside, and then grind it down smooth when cured. When you're trying to grind down the edges on the back side, a round sanding attachment for an electric drill with the pad and sandpaper mounted reversed (so the grit is facing you) can be inserted into the hole and used to grind the back side from the front side.
Helpful hints: Buy a batch of cheap disposable paint brushes about 1 to 1.5 inches wide. Buy a box of cheap rubber gloves. Apply the rosin with the disposable paint brush and throw away the brush. Wear the rubber gloves, and keep changing them after they get rosin on them. When grinding, wear long sleeves and a fan blowing the dust away from you will help. Buying several graduated mixing cups can be helpful also.
I like to buy the rosin and fiberglass cloth at a large boat supply house as it is a little cheaper than the kits at Walmart, but the kits (maybe about 2) will work for this.
Let us know how it turns out.
