I know this isn't the news you want to hear, and it may not be fair or reasonable, but you will not find a adjunct instructor position without a Master's, and it will be challenging to find one without a doctorate.
However, you might look into online training services like computertraining.com. Since you're certified, then that might be all they need. Better if you're willing to add more certifications.
Good luck,
