I NEED help with my vehicle.

I had my car at the place I work at (subaru dealership) it's a 2013 hyundai elentra gt. I needed to take off my exoust manifold. And one of 8 bolts got stuck inside of my block. The only solution seems to be either buying a new head for my engine or sending it to a machining shop. I'm 17 don't have much money left (spent it all on the car) what should I do in your opinions. Whatsvthe best corse of actions?
