teaching/ class recital?

/I have a small group.  But they're a fun group.  The beginners are just so darn cute.  It's so nice to see someone finally get something or struggle with something that after all this time seems so... easy to me but so hard for them.  :)

My feet are killing me.  Even in my dance shoes those concrete floors are hell after teaching for 2 1/2 hours.  I wish I could find a better space - with sprung wood floors *dreams*, but the rent is cheap,  *sighs*  - after costs... I need to make a little something.

I raised the idea with my 'advanced' class of maybe doing some sort of class recital.... they seem interested.  The logistics of it could be a problem though.  Would I charge for rehersals? Would I sell tickets for the recital?   Ideally of course I'd do neither but the space won't pay for itself.  I would be happy to spring for the cost of the recital but...if I provided door prizes and/or refreshments  in addition to having to pay for the space.... it could really add up. 

Those of you who have done this before... tell me how it has worked for you... I'm rather naive about these things.  The only performances I've done have been solos at free events (so far)
