Move my wedding date?

Not crazy, definitely doable but would be rushed. I would look for a venue and see when they have availability

If you can find the key vendors like venue, catering and photographer then go for it

No your not crazy, it’s definitely doable you might start to feel overwhelmed or rushed . Only other thing is making sure the venue is still available and that you give any guest that’s from out of town time to get there accommodations together

I think that's still doable if you find venues and the major vendors right away
