I need Wonklets

There was the time, only a few years after I'd started entertaining when I had a booking in this nice house. Lovely front room, about 8 or 9 girls who'd seen me before. They were in a state to have fun and after half an hour the father wandered in. I hadn't even started! I blushed, apologised, said how I not got round to doing the tricks yet, blustered a bit. He soon stopped me and said: "Well you seem to have entertained them pretty well to me!" I had the sense to shut up then as I realised that I was no longer a magician - I was an entertainer. A learning curve indeed.
Many years later I reckon I'm a stand-up comedian for children. I started by doing at least half a dozen tricks. Other magicians would ask how many tricks you do! Now I do one - maybe two. And still entertain for up to an hour before a break. Even with 3 year olds.
I am thinking of starting a sort of agency. When I'm booked there's no one else round here to recommend. How will I select other entertainers? How will I judge which beginners will be good?
One simple thing is all I look for. Do the kids like them? If so it doesn't really matter about the magic - it will come! Kids will laugh and cheer - especially if you're clever or funny. But if they really like you - that's real magic.
Anyone in the Hereford area?
