Starting a reptile rescue is a great idea but it does take a lot of planning and a lot of work to get it off the ground and at a place you are actually doing some good. I'd say in the next 3-4 years, find yourself a building, go through all the legal mumbo-jumbo, begin saving up money, and ask around about possible volunteers (you won't be able to do this on your own.) Get a website planned as well.
I would love to do reptile rescue as well. I see tons of ads on CL every day with people trying to sell their snakes and lizards off because they are moving or just don't want them anymore. I've taken in (technically) 3 snakes already, and two are going to my friend.
Also, make a plan for yourself. What kinds of animals will you be set up to take in? Me, for instance, I can't take in the big snakes because I simply don't have the space or the ability to care for and handle such a large snake. Take these things into consideration. I'd get a building with plenty of rooms so you can separate your rescues. It would really suck if all you had was one room and you had X amount of snakes ready to come out of QT but you had to bring in a new snake and reset the whole clock.
Good luck to you! I hope you can make this reality in the near future.
