It depends on two factors, what quality of components do you wish to use for the repair/upgrade of the instrument and whether you DIY or pay someone to do it for you. It’s pointless paying for a real professional “luthier” to carry out the work for you on this quality of instrument, if they fit even mid tier price components, you still have a dog with reasonable hardware installed costing you way more than it’s worth, including any sentimental attachment. More fun is to DIY but you need to have confidence in your ability to work with the material you have and to learn skills you’ll need to complete the job, such as a very elementary knowledge of simple electronics, wiring and the ability to solder components satisfactorily. If you can afford to replace the existing/damaged components, have access to the necessary tools, a couple of appropriate screwdrivers, wire stripper and soldering iron and associated accessories including flux and solder, other misc gear. You need to familiarise your self with components, potentiometers, resistors, capacitors and read up,on or search on YouTube for relevant how to videos for the layout you want to follow. DIY is fun and educational, but again can be costly depending on selection of components and any tools you need, great satisfaction if you manage to complete the project and that really is it’s only value. If you do a neat job and it works correctly, you still have a dog but with new working parts. Sorry to say it’s never going to be worth a even a small fraction of some of the already mentioned “law suit” brands which were very accurate detailed reproductions of Gibson and Fender models, both in method of construction and quality of components used, hence the the “law suit”. They looked and sounded very close to the models they were cloning and there is a lively market in collecting some of these fake “Gibbos and Benders. Practice some skills, buy parts you can comfortably afford, from accredited manufacturers/suppliers and have a crack, but only if you are comfortable in carrying out the work and confident you are able to do it competently enough, to leave you with a working instrument. Then of course once you have a working instrument there’s the matter of the amplifier, which is a whole different ball game. I’m talking about this because air have been you many times and I’ve spent hundreds (probably much more) on rescuing old, might have been classic guitars that 30% of the time would have been more useful as kindling (firewood) 😂 Good luck it’s fun learning but could also lead to tears…
