A good friend of mine gave this savvy advice for submitting a funding proposal to a businessman:
One idea however would be to include your nice flyer in a printed nicely presented proposal letter etc and post in A4 envelope. Then send it all by email the afternoon when the mail should have arrived and refer to the hard copies he should have received. This is a chance for him to read it in hard copy, which he'd much prefer than reading it all in electronic email attachments (he's not a fan of big attachments), and then also a chance for you to include the nice looking flyer, and your business card etc. The photo of you in the flyer will help him to visualise who he's supporting, which is important.
Good suggestions, don't you think?
