If it is creating a map of your own that interests you, there most DEFINITELY be people around here who can help ...and possibly make one if you ask nicely Mapping is what we are all about here at The Guild, The Mappiest Place on the Web. And welcome you are indeed. You will find all sorts of tutorials here, for all sorts of programs, admittedly most of them are for Photoshop and the Gimp. Following these tuts will be the best way to get from here to there imoho. If you want to get there quicker, I would suggest that you start a WIP (Work In Progress) thread with your work as soon as you start a new map. This is indeed the best way to get access to the vast knowledge base on all things mappy that the membership brings to the Guild. Don't be shy about asking questions either because we are a very freindly group and the advice you will receive will get you there much faster.
And you will be surprised at how fast that initial journey can be, and the results at the end will be well worth the trip, I assure you.
