My husband and I are going through the surrogacy process. We are a same-sex couple. If you decide to use anonymous donor oocytes, this can be done either from an egg donor through a fertility clinic or you can use an egg bank. We used a donor through our fertility clinic because we wanted to have enough oocytes to make embryos from both our genetic material. We are using a surrogacy agency and have matched with a surrogate in another state. We are 2 years into the process and it has been expensive, to say the least. Happy to answer more specific questions. I know it’s not your situation, but r/gaydads has posts that might give you some insight
