I agree that life issues can get in the way of caring for our pets, and when that's the case, rehoming them may be the best option. Particularly if you're facing financial constraints... you need a steady income to provide the best food and possible vet care to your dragon. You're doing the right thing - putting your pet's needs before your own feelings.
As Karrie mentioned, though, rehoming your pet can be a job in itself. You want to make sure your dragon is going to a well-educated home, not into a bad situation. Finding an established reptile rescue would be the easiest way to do this; they handle all the interviewing and adoption fees. Contact your dragon's vet to see if they know of anyone in your area, or contact the local herpetological society (most states have at least one). Even calling around to local animal shelters might provide some leads, though most are not equipped to take in exotics.
Try calling nature centers and science or children's museums that have live animals on the premises if you don't have a zoo nearby. Most of these places, including zoos, will not take pet donations- they are usually offered far more animals than they can take in each year- but they might know someone who could help you with rehoming.
I agree that you should definitely avoid Craigslist or Facebook for rehoming; they generally do not attract the quality of owner you want, and at worst are trolling grounds for people looking for an easy, cheap meal for a larger reptile or for people who want a free animal to torture and kill.
Good luck with finding your sweetie a good home!
