I've been looking around at Boudoir photographers(and once upon a time before I was paid for sex I did have such a shoot). Whilst their packages are great for a one-off, I don't think they are suited to those in this industry who want representative shots, several times each year. Most ladies already have their own lingerie and personally I wouldn't want my hair styled or make up applied professionally since I want to be wearing the sort of make-up I wear when meeting clients, and my hair the same.
This is all why I don't think the type and price of the service the OP offers will ever be very popular with the ladies here.
