If by "ride" you mean around the pattern you will have a good time. Why
not just go down to the local FBO and have an instructor take you guys
up.
If by "ride" you mean to take you somewhere, that requires a very
specific and hard to aquire certificate (135) that fewer and fewer
small aircraft operators have. Even if you share costs, if you are the
one creating the schedule and the pilot is just serving your schedule,
the pilot will have legal problems without a 135 certificate.
