Syag, first and foremost, Mazel Tov.
1: I thought that the Sheva Brachos is by the girl’s side?
2: Contrary to popular belief, there is no chyuv whatsoever to make a Sheva Brachos. It is only if you happen to have a seudah that fits the criterion that you make the brachos.
3: As I have posted before, your best bet for a sponsorship is to contact www(dot)gatesfoundation(dot)org.
🙂 Mazel Tov again.
