I think it’s doable , yes, electrics needs checking out, then new kitchen and bathroom, that’s easy enough, then it’s floor coverings and decoration, check for damp obviously.
Windows seem fine but boarded up, maybe needs new windows. Probably about 50 grand max if no nasty surprises. But I think you could make it habitable easy enough. You could probably get away with 20-30, depending on what kind of finish you’re after.
I don’t think you need access to builders. Someone like Wickes will do your kitchen and bathroom, plenty of double glazing folks around, as are electricians and damp proofing.
Flooring and decorating is also easy enough.
I think as long as you have the budget it would be fine.
