Hey there!
With your given budget, this trips seems doable! For more details, I have attached an article on the budget, stay and places to see in Seychelles.
Hi, Seychelles can be done even within budget .
The flight from Mumbai to Seychelles itself would cost approx 25k per person on a round trip fare. You can then look for Air Bnb's and there are plenty of options within 5-6k per night . Or else - you can get a quote from Travel Triangle . They have a lot of packages based on different budget types.
