I completely agree with Cataholic.
As someone who has job openings to fill on a regular basis, I get hit with 300+ resumes at a time. I HAVE to make snap decisions and quickly too. I imediately eliminate poor grammar, typos, unprofessional looking replies (including email addresses. Though I don't have any problem with what server anyone uses...its just "cutsiepoopsie@aol doesn't make for many points.) I also eliminate "blanket resumes" when it's clear they are just sending resumes to everyone!
Do the extra leg work of using the person's name and not just HR Dept. Courtesy also goes a long way. I think "Please email me with a good time we can meet." would get your point across. I'm not crazy about the "if you are interested" phrase. Sounds like you are looking for them to come to you. I think a more proactive phrasing would be stronger.
Good luck I know it sucks to be looking for work and must be even more so with your challenges. Keep the faith! Somewhere there's a perfect match for you.
