Are your job posts being carried through to Jobslinger? Ads on the Volition board or the MSPA board should transfer across. I know you are not a SASSIE company, so it wouldn't be just automatic from there. Obviously you are welcome to post here, but Jobslinger does not pull from our board.
You might post on Craig's List in those areas. Just make sure it doesn't sound 'too good to be true' and get flagged as a scam.
