Depending upon where you are, and your availability, I've occasionally offered cosplay help sessions where either I go over to your house, or you drop over to mine and we work though creating a costume. One friend of mine (who had never sewn anything in his life) successfully created two costumes with my assistance - basically, we generated the pattern & determined the fabric / notions requirements, then he shopped for required items (based upon my estimations of what we needed), and met a second time to cut & sew the pattern we'd drafted from first meeting.
