I need someone for a short clip on my YT videos

We have a company for GCSE English and other things related to language learning and would like someone who can create a short 30 second to 1 minute clip (which we'd put at the end of our videos). In this clip you would encourage people to subscribe to our channel, visit our website and to buy our e-books and T-shirts (we can send some of those for you as a complimentary gift). We are looking for someone British (GCSE is a British exam), photogenic and who can generate a lot of sales for us.

It would be preferable if you could also edit a few seconds of a cursor clicking on our website and clicking on our products in your clip alongside the voice over, or we could just hire an editor for that.
