So the plan I'm having to fix this is fiberglass. this is DIY project I don't do this for a living but I've been doing a lot of reading and I'm pretty handy. have some but little experience on auto body just need some guidance.
So my plan here is get the rust out, do some treatment on it. Epoxy prime and seal body work prime and paint. What I need help the most on is if you see in the picture at the end of where It stops chipping off has a panel that's not reachable You could kind of see a hole. I don't know how far I should go to where I don't screw myself over that I cannot use fiberglass anymore but at the same time I don't want this to come back.

That is far worse when you start digging into it, The rust will extend far into the panels on the back side far further on the inside than your seeing in the out side.
Its way too far gone for a simple cave and pave with Fiberglass.

You need to get into it as far as rust extends, cut out the rust and weld in new metal. Not what you wanna hear that but its the truth!
If you want it to last a while longer than a few months any way.
if you just build that up with Fiberglass expect it to return in less than 6 months Not saying it will just saying I wouldn't be supersized.

Around how much do you think that would cost just to get someone to cut it get the rust out and weld a new piece

imo, more than the value of the car IF you can find someone that would touch it.
im gonna guess ya live in a state that uses road salt. the right wheel well probably isnt far behind this one. looks like thats a monte or another w body.check the rear strut towers. the w bodies are notorious for them rotting out and that,imo, would be more important to take care of.

This is why many of us learned how to weld in patch panels. :wink:

Impossible to estimate with Rust, as I said it is going to be worse as its dug into!
Cars/Trucks rust from the INSIDE OUT! BEWARE any one who tells you different or gives you a simple X price for a repair they don't have you or your cars best interest at heart they just see a quick buck to be made.

Cost of repair will greatly Depend on how far and how deep the corrosion goes and as said above other areas May need repair which may be far more critical for your safety and that of your passengers as Steve said.

This is one of those types repairs that if you have to ask how to do it its probably beyond your scope of knowledge and skills, The tools and equipment necessary to perform a repair such as this are extensive and NOT cheap! the subject has been covered in detail, I suggest reading all you can find in this section including the stickies at the top of the page then doing a search of Rust repair will return a lot of material for your reading enjoyment.
