I started out just buying a gun or two just because I happened on a good deal. Had 5. Went to war and used several for the purpose intended, kinda lost interest for a while. Then I had the means to start back shooting ( was rifle team member in military school) and bought a couple more, then I went completely berserk, and got into collecting. Now I have 42 hand guns, more long guns that I can shoot, and am taking a long look at shotguns.
If you can't afford professional help, start with the highest quality gun you can, no matter which kind. Quality will always come to the top. Enjoy the hunt. I get as much pleasure out of finding "just the right deal, at the right price" as I do having the gun. It's a sickness that I hope to never be cured of.
Now I have several relatives just waiting for me to croak, so they can inherit my collection. I also told them that if they piss me off I'll be buried with the guns. They treat me good!
