Talk:Advertising

I have been put in charge of promotions / advertising / sponsorship / fundraising for our Con.

This was a strategic decision, with the idea that I could discuss all of these options (as appropriate) all at once with potential parties I make contact with.

My question is, for cold-calling on advertising, does anyone have any tips? I would love to read a typical cold-call type letter that you might send to a company to seek their interest in sponsorship...
