Sounds like it could be a good side project but like the other person said, impossible to scale so don’t expect it to pay all the bills. Plus this seems like a really small market that would require a lot of time and effort marketing just to break even. But if you’d enjoy it in your spare time, why not?

What’s your business name? I’ll happily give you a review! I’ll be sure to mention the fact that you tried to buy reviews online that way people will know to stay away from a dishonest business :)
