I would expect for that price to be around $65K today. But who am I to know? There are many good contractors out there who I am sure could give you a free quote. Ask people at work, neighbors and friends to see if they could recommend anyone. After you found someone, get some referances to check out past work.
Unless, of course, you are wanting to get the job done yourself. You could save alot that way. But you'll be using your time and getting a lot of headaches for the money you save. But in the end, the satisfaction of getting something done on your own could be priceless.

Basics - buyers (and homeowners) want a good roof, heating and airconditioning system and plumbing and electrical systems that are up to code.
Also depends on how the 2000-2500 feet is configured. Some older homes have floorplans that are obsolete and need to be retrofilled. Open floor plans are much more popular today. Finished basements add value. So you need to make sure yours doesn't leak, and you have a way to access the major systems if you are planning to finish it.
Most buyers want an informal family room, less important is the formal dining room. Home offices have become popular so depending on the number of people who liviein the house, maybe a bedroom can be converted. Just make sure you have cable, FIOS and/or DSL access.
