If you don't get any replies right away don't worry about it too much...people tend to mull things over before committing to do it (in their heads) before contacting you. In the meantime, I would suggest that you make 4 more posts (on anything really) but look at some other maps here and say how much you like them or something like that. Once you get to five posts then you can send private messages to the folks here and maybe one of them will answer more promptly. I'd start in the Cartographer's Choice and Finished Maps sections.
