Not sure if there are any of these agencies in Orlando, but try Manpower Professional (I've worked for their Las Vegas office and are pretty decent). Found 3 offices, not sure how close to Orlando, but here they are:

Normally either agency could dispatch a tech same business day. Wish I could help you more, even by troubleshooting it myself but I live in Vegas and you certainly wouldn't want to pay me the rate to fly out Red-eye. :) Best of luck. Let me know how it turns out.
