Marketing needed for 12 improv comedy classes this year

Hello,
First of all, my need is to sell 12 classes over the next year. One of which will not be able to happen as it is next weekend, I believe. So I teach improv comedy weekend intensives, but in cities that are either sparse of such activities or have a fair amount. I have done classes in two out of the three before. The main reason I am in huge need of someone to do the marketing for me is that I have begun a masters course and the money I get from the work will feed me. This leads to the other point: I have no money, which means the small investment I wish to make into getting someone to do this needs to lead to sales.
I do not know whether you can help, or if want to, but it would be appreciated. Whether you can pass me onto someone that wants a little bit of work or if you can take it on, both are good. The amount I wish to offer is £480, in four blocks.
