Hey, I took a locksmithing course from Foley Belsaw. You can make a tumbler rake out of several different items. Don't go hiring a locksmith yet until you at least give it a try.
The most perfect one I ever made was from a small modelers hacksaw by taking an old blade, dremeling down the teeth except for the last one and grinding deeper into the shank to make the tip of that last tooth like the end of a single barb harpoon.
If the tip is loose enough it wiggles in there (showing it's not seized by a twist) sometimes you can get them out with a heavy duty paper clip, smashed flat at the end and then filed to a harpoon tip.
If you have fishing equipment, get a large hook and straighten it out best you can. You'll need to blunt the tip, only the barb needs to be sharp. The point has to push the tumblers back home for you to get to the end of the tip. (A long skinny hook works best, the cheap china crap hooks)
Get a bright pen light and see which direction is the best way to attack it.
Sit down on a short stool or seat so you can look straight into it without fatiguing your back or neck. A pair of reading glasses are beneficial as well as an extra set of hands.
It might take a minute, but I'm pretty confident you can get it.
The biggest trick may be seeing what you're doing without getting in your own light. Once you've kinda oriented yourself, don't be afraid to work by feel. Try to see in your mind what you're doing, a great deal of lock work is done by feel.
Also, I
thiiiink that Harbor freight sells a set of picks that should come with a couple types of rakes.
Besides, if you get the pick set, you might get bit and start to find locks interesting. Locksmithing doesn't take up much space, equipment is cheaper, and there will always be a market for your skills.
It's a cool hobby and you end up being the 'hero' in unexpected situations.
I wish I was there to kinda show you, but they have youtube for that stuff nowadays. LOL
Go make you a rake and have fun!
