How should I go about looking for a sponsor/investor for my novel Friends 2 Lovers?

I've worked hard on this book and now after so many reviews and people telling me before I put out part 2, that all my book needs is a little more editing because no one is perfect. I'm looking for help hiring a editor to look over it with me, helping me to correct some of my mistakes and sentences. I've found the editor but I'm not working right now. So I'm looking for help. I'm asking now for some tips, on who I should try contacting about it.
