When and if you do any cold selling and walking the streets what do you present to the potential client?

Just Business card?

Portfolio? Flyer with services listed? Color or black and white?

I am just starting to get my feet wet with the freelance thing and do not want to spend $1000 on color brochures but will spend when necessary.

What did you do starting out?

If you do have a flyer or brochure that you hand out what do you include?

Thanks everyone for the excellent learning experience!
