Question Quotes...possible?

Hello!

I have a token based survey where the person will be rating 5 places. There is 10 questions I need to ask them about each place. Now the hard part I am having is that I only want each places to be rated 20 times. I have 4 arrays setup, asking the 10 questions for each place.
I need a way to make it so that limesurvey randomly picks 1 place out of the 4 and most importantly when a place reaches 20 ratings it is no longer a choice.
Any suggestions or solutions to what I am trying to do?

Thanks very much!

Bryon
