Sounds like a fun idea. It'd probably be good to consider someone you've seen regularly since the two of y'all would already have a great rapport. I know I shower a suitor who books me for a multiple day date with an abundance of adoration and go even further above and beyond to ensure all his desires are met.
Also if it's understood that you are seeking an exclusive date, a reputable and professional companion would not be lurking around trying to pick up anyone else.
