My suggestion is to first contact a couple of different timeshare brokers and compare their costs and commisions. The Timeshare Store, sponsor's of this site, http://www.dvc-resales.com/, are an excellent place to start. Shontell Crawford, formerly of the Timeshare Store, has now started her own business. You might want to compare costs with her:
