Who can help edit my PhD thesis?

Hello
While writing, grammatical and spelling mistakes are bound to happen and I strongly believe in editing. But with my job and family, I am unable to edit my draft and I can’t send it to my supervisor without an edit. So I am simply writing to inquire about any proofreading service that might be of use. And how much will they cost for editing a 50000 words thesis. I would appreciate genuine responses.
Thanks
Fin
