Hi Brii and welcome

Good on you for having such a focused set of ideals in what you would like to do with your life and photography.
I certainly wish I had been hooked alot earlier
It's all good here with lots of friendly advice.
I have a Polaroid Supercolor 635CL in my small collection of cameras.
I found it in a 2nd hand shop in Manly, Sydney in its origianl box (currently lost but here somewhere in our household mess).
The strap has never been removed from the plastic packing band and it use to scrounge around for film cartridges, but haven't for a while. I got into Polaroids when I saw an article in a Photography magazine where a guy was taking the freshly developed prints and pushing the emulsion around with a bamaboo meat skewer for some photoshop style effects. I thought it was kind of cool, so hunted this thing down, did quite a lot of shots and then scanned them. I even did part of a wedding shoot with it and the bride and groom loved them!
Check out eBay, there are a few here:

Welcome again! Don't be afraid to post some images and ask questions.
