Temp Private Driver

I know there are some related posts about this already, but I can't seem to find them right now and I also wanted to ask about a specific situation.

I've moved to Bahrain and my family (wife and son) are following in about 1.5 months. They're coming for a visit later this week and will be here for about 2 weeks.

I'm looking for a reliable, safe driver that can speak English and has a sound car to take them around in while I'm working. The problem is that it wouldn't be regular - more as agreed a day or two in advance and at various times during the day.

Any recommendations on drivers?
Also, any suggestions on what the proper rate is for hourly/daily rates?

Thanks!
