Donation for lead promotion

This is what a business in United Kingdom was looking for in their banner ad design

I am looking for a banner that can be placed on our emails, quotationion forms and invoices.
This is direct to existing clients and new, we are offering a charity donation for any genuine sales lead enquiry an existing customer gives us, this cannot be them but a contact they may have or friend etc etc. I want a fun/cartoon style graphic with the slogan
"A donation for a lead" being incorporated in the design.
It should be colourful, bold and in directed at B2B.
We would want a full edit version high res pdf so we can adjust to fit on various stationery etc.

The charity at the moment is wishes for kids and hope to have another charity on board as well. Read more
