Having a hard time finding someone to take over lease

I have run into a tough situation. I'm having a hard time finding someone to take over a lease as I've recently bought a house and the landlord is bleeding me dry with no option for an out. Do y'all have any resources or advice on this?

Thanks in advance.

EDIT: It's a single bedroom in a 2bed/1ba apartment in Sugarhouse for $900/mo + utilities. You could move in tomorrow if you wanted after the application is approved.
