Alright, I'm going to do as legion and zeekay have suggested.
Right now I'm looking at this crimper: Amazon Link
This pin removal tool: Amazon Link
Less sure where to get pins (the ones on amazon have terrible reviews), sleeves, and shrink wrap.
Where do you guys shop?
You bet. Here is a table of tools, connectors, terminals (pins), wire, and cable wraps. You don't need everything if you just want to try it out, but these tools and parts are highly recommended if you want a good result.

Ok, that seems like a lot. But you do not need everything to get started. If you want you can sleeve your existing cables and save a lot of cost. It is a little more annoying and time consuming but it is the cheapest option as you do not have to buy wire, pins, and connectors. If you are going to be working with wires though, you are going to need the crimpers and some pins. You are going to mess some up while learning. I still do and I've been sleeving for a little while now.
If you are going to just sleeve your existing cables, I recommend going with the Teleios Sleeve as it'll be easier to feed onto the wire. Or if you want to use paracord you'll need to buy the Paracord Theader. If you don't, the pins will tear up the paracord and it'll look like crap. So the only tools you'll need if you want to go with Teleios are the pin extractors and cutters.
If you want to make extensions, you'll need to buy both male and female connectors and pins. This is a great place to get your feet wet as the pin outs between the connectors are 1 to 1. Watch this video from PCPartPicker. You should also take some time and watch all of Lutro0's sleeving tutorial videos. He runs MainFrame customs and does a great job at providing and explaining everything you'll need to get started.
I hope this helps, if you have more specific questions please let me know.
