bro nobody gonna waste his time and do this job for you. you either do it yourself if you got a copy of the game and familiar with reverse engineering and cracking or forget about this thing and move on because its useless
Try upwork and look for people who are new to the site. They'll usually accept less just to get their first job. Just make sure to do flat rate, hourly they will try to scam you
I don't see the reason exactly *why* you would wan to reverse engineer the game?
I'm also wondering why you're asking on the darknet. I guess the company who owns the copyright is still active? There's enough places on the clearnet where they wouldn't really care about that either.
I want to reverse engineer the game in order to imporve a certain aspect of it. Yes, the company is still active so what I want is either illegal or gray area at best. Even though I want this improvement only for myself and the chance for legal consequences is practically zero, I think the reason I couldn't find anyone on the clearnet so far and only got low quality/scam offers is partially because those who can really do it don't want to take the job due to legal/ethical issues. That's why I decided to ask on the darknet as well, hoping that someone gives me better directions on how to proceed.
Depending on how rigorous the changes are you have in mind, you might want to check the cheatengine community. It's a reverse engineer tool specifically made to cheat in games, but for those with some knowledge in C or assembly it can also be used to add functionalities and small features. Eventually you will probably run an extra application next to the original game that will inject the code.
Why so important? No one will tutor you on that and you have to spend a while lot of time to figure it yourself whereas you could make it known on clearnet
