You should cut costs. BTW, 15 grand is nothing. Some of the weddings I’ve seen are ridiculously expensive, and it just makes you wonder what people are thinking, honestly.
Just get a decent sized hall, have a select number of invites, spend money on some decent food and call it a night.
Mehndis can be done at home, and really should be done at home…
And the valimah should be modest anyway.
