I've raised £1500 to help find a new flat and move out in time

I've been living in the same flat since 2015 and now the owner has decided to sell the flat, so I have 3 months to find somewhere new to live, raise the first month's rent and deposit and move in...
Because the flat was unfurnished I have all of my own furniture to move as well as all of my belongings.
I'm self-employed in an industry that's been hit just as hard by the cost of living crisis as everyone else and I'm really worried I won't be able to get this money together on my own.
So I'd really appreciate the help if you can spare it x
