I have addressed this concern via PM but I'd like to share it with other SaleHoo members, hope you don't mind. :)
Missguided and Pink Boutique currently do not offer wholesale programs. On Missguided's official website, they have stated that they do not authorize anyone selling their products. Their items are only sold through them.
However, they offer affiliate programs for free! Link hidden: Login to viewLink hidden: Login to viewLink hidden: Login to viewLink hidden: Login to view
AX Paris is open to resellers. Check out their wholesale program here: Link hidden: Login to view
If you are looking for other products or brands, let me know and I'll try to locate suitable suppliers for you. :)
