Uline does do printing on their poly mailers (at least the solid white ones) -- although their minimum for ordering is something outrageous... like 10,000. So, unless you are extremely optimistic I'd go with JDR's suggestion. As well, there are other companies online that will do bag printing - just search around for them and get in touch with someone at the company. www.aplasticbag.com, www.excellentpoly.com, etc. As well, as you just start out, perhaps forgo the bags for a larger nicely designed sticker -- and then commit to a bag order as a graduation present to yourself.
