A couple of years back, I decided to try my hand at archery. Like you, I didn't plan to archery hunt, etc. but thought that the ability to do so would be a good skill to have. Mostly, I wanted to target practice and learn to use the bow in case I ever decided to hunt with it. With that in mind, I bought an older compound bow at a flea market for $25. It was pretty much stripped - didn't have an arrow rest, sights or anything else. Also, the string was worn and needed changing, along with the cables.
I took it to a local (now closed) archery shop and told the owner that I pretty much wanted what you want - just the basics to be able to shoot it. First, he checked it out and said that I was lucky because such 'finds' often have a cracked limb. Mine was solid. He then said that I was extra lucky because the draw length of that bow just happened to match my own, personal draw length.
He then proceeded to set it up with just the bare minimum for shooting a compound bow. It got new cables, a new string with peep, basic sights and a basic arrow rest. They set me up with a handful of arrows of the correct length and I picked out a small, cheap quiver, cheap wrist guard and a release. All told, iirc, it cost me just over $130 just to get my $25 bow into basic, working order. That was still probably cheaper than having a place like Gander Mountain set it up as this guy tried to keep his prices reasonable because he wanted to get more people into his sport. This still didn't include a stabilizer (someone gave me one) or a cable guard - which I still don't have and would need if shooting the bow a lot.
The shop owner also checked draw weight for me and said that the actual, peak draw of my bow is around 65 pounds. He also let me try out (just for comparison) a newer compound bow that was about half as long as mine, weighed significantly less, was easier to draw but had a higher peak weight. Of course, what I spent on my bow and accessories would still have gotten me only about half way to buying one of those.
Honestly, I haven't shot it that much because when I have time to shoot I tend to break out my firearms, instead.
