That's OK, leave it up to me.
He probably just ran his engine over redline for an extended period of time.

Look. I'll try to be nicer this time
You are lucy in that the gs500 is an older and simple design (and aircooled.)
However. The very first thing you need to do when rebuilding an engine is Pay Attention to Directions. The second thing you need is PATIENCE. you've already given yourself a time limit - that's bad. Hell, it may take you 3 weeks just to get the parts you need. You need PATIENCE. If you don't have time to do the job right, then wait until you DO have time. Order the parts now, and work on it when you have time.
That being said, how can you order parts withoug knowing what needs to be replaced? Since your bike is air cooled it is also highly likely that you overheated the engine and galled your pistons. This would require replacement of the pistons and a reboring of the cylinder walls. The quote that you got for the rebuild sounds like this is what you need. In which case, you are SOL, because you need equipment that costs well over $3000 to do this kind of work.
In short, you have to take the engine apart, and measure out all of the bits and pieces according to the specs in the service manual (Using precision measuring decices like a micrometer) and replace what needs to be replaced. You will have to (Probably) take the cylinders to a special shop to be rebored. You will have to replace all of the gaskets and crush washers that are in there. and when it comes time to put everything back together, you will need to torque every bolt to specs or risk another failure.
I think it will take you longer than 3 weeks, and not having any experience, i'm going to say that you will probably mess it up or give up halfway through. I also think that if you do the job properly, it's going to cost you at least $2000 anyway to buy the tools and do everything correctly. In sum, take it to a professional to be fixed.
Maybe you can take it to an Independant engine rebuilder and have him do it for you. It will probably cost less than the dealership wants to charge you.
