Biblical Arts Festival
Educational Ministries used to have a book called "Biblical Arts Festival" that had things like pottery, weaving, and metal smithing. Also, "The Life and Times of Jesus" by Readers Digest had some great information on occupations. Other resources you could use is a good Bible Atlas.
Some occupations you might think about are pottery (perhaps you have a local artist or community college that you could use?), weaving, fishing, shepherd, priest/rabbi, to name a few. Remember Lydia was a seller of purple cloth! You could have lots of fun with this one!
