It might be worth while to create a new post where you specifically write what arrangement you'd like to have. For example "x" hours of time including dinner, drinks, MSOG, etc for "x" amount of dollars. Ask for replies to be via PM only so women who do reply are comfortable the arrangement is private.
I think you've made a reasonable request and only women who are interested need reply. There is bound to be someone who would like the company, dinner, romance and a few extra bucks
I hope it all works out for you
