Bridal dress

Dear Sirs, I am about to open an online store for evening dresses and wish to become your retailer, I am currently working on the site and currently finishing deals with other well known designers to promote on my site. Can you please advise on the requirement to become your retailer, price range for evening dresses as a wholesale ( mostly modest if available), can you take special orders to have a jacket and veil as well for special dresses?, time to ship?, etc...
