#5 definitely!!! I think the ladies working in startups will definitely appreciate it! Startup schwag rarely fit me properly :( and most of them are just a logo slapped onto a T-shirt. Would be great for team morale! Plus, nice swag like rovio's angry birds plush toys, t-shirts etc are selling like hotcakes http://disrupt.techcrunch.com/SF2011/2011/09/12/angry-birds-... there's definitely market validation for that idea! I definitely believe in investing in gd schwag and who knows that might even become a source of income for a bootstrapping startup :)
Swag can be pretty big. It is a difficult industry since margins are really thin, but I think people are willing to focus on a service that helps them to outsource some of their swag needs in order to focus on other aspects of their business.
