I don't see any point in giving up a snake for financial reasons unless you become actually homeless. You can stretch feedings out to once every 2 weeks. Rodents are usually cheap unless you live somewhere really isolated. If you choose to get a new snake when you find a job again, you'd end up spending way more than you'd get for this snake and enclosure. And you wouldn't get enough for the snake to make a big difference in your financial situation.
And, yeah, try contacting a breeder or putting out a help needed ad on craigslist or something. I'd toss a few frozen rodents your way if I saw an ad like that.
I have a friend who used to sell all his stuff when he needed money. Then when he got some money he'd buy it all new again, spending at least double of what he sold it for. Used to drive me crazy seeing how little financial sense that made.
So hold on, don't do anything drastic until you're sure it needs to be done! Don't rush into a decision.
