Shannon - welcome to the fashion industry network.
I have a fashion directory website called Apparel Search and I do not currently have a section for your type of business. I have stylists, modeling, fashion weeks etc., but do not have a specific section for companies that help manage back stage issues for fashion shows. Maybe I should create a section and list your company. Do you have a website?
If you have any questions about this site, please let me know.
Also, you may have interest in my photos site at FashionWeekPhotos.com If you attend events that are not listed, maybe you can tell management at the events to send me photos and I can add a section to promote their events...
