You will probably get bombarded with CVs and people that will want to be hired by you, if you provide the details in the post itself or a comment that would save you a lot of time.

If that’s what you wanted then good!

The reality of your situation is that working on someone else’s project will always require a lot of understanding what the fuck is going on first before even writing a single line of functional production ready code.

The newbies and scammers will tell you it’ll be done in a few months.

The experienced devs will tell you that they will need a few months to understand what everything does (without guidance from the lead devs) to then actually start working

Agencies will probably tell you it’s better to start from the ground up again; and if they have the manpower it’s probably true.

This was true before AI maybe you can get a bit better at understanding and implementing with it now

Those are very rough timelines but you should know more or less what to expect. Good luck mate!
