First off, welcome to the Guild! Second, are you requesting help making a map or do you wish to commission someone else to make it for you? If the former, you'll want to start by spending some time getting to know the tutorials sections. There's plenty of helpful walk-throughs there to help you get started. Once you've tried one or two, post up a WIP thread showing your work and ask for feedback. If the latter you'll want to place a classifieds add in the Map Requests section. Be sure to read the sticky in that section first though, as it covers what sorts of things you ought to include in a commission request.
