I'm not too familiar with Ellie Bean's processes, but can I put in a quick plug for Boutique Beauties?
We are a modeling listing site, but the difference is we make the whole process a whole lot easier for both the boutiques and the models. Everybody who registers on our site gets their own account and controls their own info. Boutiques are able to communicate with models, and we eliminate the middle man and having to wait for emails to go back and forth between 3 different people. AND, not only is it free for boutiques to list with us, but they earn points for every booking they make and those points can be cashed in for rewards like gift cards and shipping credits.
We'd love to have you join us! Just let me know if you have any questions!
