So, I’m going to be upfront, I can’t offer anything in turn so I’ll be asking for you to do a decent amount of labor for free. At best I can offer you a cheesy coupon I found on the Internet for free for services or food you may or may not like. Anyway I’m wondering if someone can do some vector or 3D rendering for an article I want to write? It’s no big deal, you don’t have to say yes, if you don’t want to do it I’ll either work around it or file it away for a later time.
