Different versions of cartoon mascot needed

I currently have a mascot for a website which I need created in different sporting scenarios involving horse racing. I.e. to have him riding a horse etc.

I require around 5 designs. I want several revisions on submitted designs until I am happy. All copyright to me and final design needs to be provided in all formats. I can provide the initial design in various formats to you for you to start.

Fixed price only please. See attached for the mascot.
