In a bit of a predicament. A local church contacted me to do some design work. They said they didn't have much of a budget so I said we could discuss payment afterwards - provided they were happy with my work. Said I wouldn't set a 'price', just told them to pay me what they could - since, you know their budget situation. I did the work, sent it to them, they said they were pleased with it, and I then received an email saying they were getting the stuff I'd done printed. I asked about payment, to which they said they were sorting it, but were a bit ambiguous when saying it. I haven't heard anything in over a week now. I contacted them again querying it again, but they're ignoring me. What the heck do I do, or have I just ended up doing 'voluntary' work?
