I don't tweet 또는 use Facebook. Without these tools, how can I get an autographed head shot of Bill for a fund raiser I'm planning?

I live in Canada. Soon to be a Legal Pot country.
I'm working on a silent auction for my local art gallery's fund raising event. I've secured a bunch of weed paraphernalia, (Bongs and stuff) and I'd 사랑 to include an autographed headshot of Bill.
