Organising clinics

[trendybraincell]

Does anyone have any experience of organising clinics or small events at your yard? I'm thinking of just starting small with a dressage clinic or showjumping etc with just the people at the yard to see how successful it is, before maybe opening it up to people from outside the yard.

So does anyone have any advice where to start, or if you've been to any clinics, what works or doesn't?!

Thanks
