How much would this script cost?

So my birthday is coming up, and I’m a poor person atm, but getting a job very soon, and I usually get 50-100 dollars per birthday. I own a TTT server and had an idea for a new simple little game mechanic.
My idea was just a very simple little panel that has some buttons on it. Each button is a class that can vary from giving you items to increasing your health and giving your weapons perks. Since I’m coming into a rough estimate of 50-100 dollars, would that be enough to pay for that script?

(Also I did try to do it myself but I only have a VERY basic, if not no knowledge of Gmod lua, so it didn’t go well)

Should be more than enough for that script. Try go on https://scriptfodder.com/jobs/ and put up your and create a job.

Sounds like what you descripe can be replaced by the free pointshop.
There many add-ons on scriptfodder that allows you to customize it to your liking.

There is also a few solutions on scriptfodder if you don’t like pointshop.
