Local printer for banner?

At last Greenlight Bookstore is on its way to opening -- we're just waiting on permits to start construction at 686 Fulton Street! We'd like to hang a banner to let everyone know the bookstore is coming soon, and in the spirit of supporting local indie business, we'd like to find a local printer if possible. Anyone know of a print shop in the neighborhood that could do a hanging vinyl banner? (Even if not, it would be great to know somewhere to get smaller printing jobs done.) If we can't find somewhere local we'll have to go to Staples or whatever, but we'd like to support the neighborhood's businesses if possible.
