I don't know who else to ask (so, if you have ideas on that front, let me know as well).
How much should we be giving the temple as the honorarium for our rabbi? It's a mitzvah (good deed) for him to marry us, so he won't accept money himself, but has said that the temple will accept a donation from us in lieu of us paying him
He has met with us a handful of times, is traveling about 25 miles (from the suburbs to downtown) for our wedding, and has offered to translate our ketubah (wedding contract) into Hebrew for us if we need it.
By getting married by this rabbi, we do get a free year's membership at the temple, which is worth thousands of dollars. I don't know if that should be taken into account when determining how much to give.
Thanks for any ideas or concrete figures you can offer!
