Private guide in Dahab ?

I'm taking a bus from Cairo next Monday which I just found out leaves at midnight and arrives in Dahab around 8:00 or 9:00 the next morning......making it a bit uncertain to plan an early morning dive that day. So I wonder if anyone can recommend either a dive center or private guide that would be flexible in time so I could arrange to go dive on my own schedule or at least not first thing in the morning ?
I'll only be there for three days (other family tour obligations) so want to get the most out of the time I'll have for diving. Thanks for any leads!

I'm currently in Cairo but could hook you up with a friend of mine if he's available. He's a very experienced private guide. In case you're interested, PM me.
