Create/design the front and back image for a custom bank note

I would like someone to create a high quality bank note for me, which will then be used as 'currency' at an upcoming wedding. It needs to be highly personalised and incorporate detail from a number of pictures which I can send you. E.g. in place of the queen it needs to be the bride, a castle needs to be in it, a teddy bear etc. etc. I can give you photos of all the things that need to be in it and then you will need to turn it into a bank note (2 sides). I can arrange for it to be printed etc, so you will just need to send me the computer file.

Hope that makes sense, let me know any questions! It would like it to be quite intricate, i.e. to be one of those things that the longer you look at it the more detail you notice....
