Good luck, but bear in mind that if it doesn't work out, this sort of thing can simply give you the motivation to find another job. I don't mean to be a downer, but I know that work has been a challenge for you to find. Now you've got your resume up to speed, and since often the one job we apply for doesn't work out, you can submit your resume elsewhere and hopefully find work.

That said, I hope this one particular job works out, since you obviously feel it would be a good fit. Good luck!
