No, there are almost no time constraints. I probably won't be actually using this map for almost three months, so I've got some time. If someone volunteers to do the map on their own time, that would be phenominal, but after reading several of the tutorials, it shouldn't be terribly hard to figure out myself. And like jfrazierjr said, there are always places to ask for help if I get stuck.

oh, you'll need an oven too, but i'm assuming you have one of those.
Okay, I assume you mean browning the paper with tea water, then simply uploading the pictures, but where does the oven come into play? Perhaps to dry the paper?
