Promote OGS on other servers?

I just love playing on OGS and wish there would be more players.

Would it be a good idea to have Tournaments with Prize money.
and do some advertisements on other popular Go server?

There could be an entry fee to cover some of the cost.
We would need to contact a few servers to see if they would be open for such advertisement and how much they would charge (unless they would happily do it freely to promote Go in the universe?)

Players who are site supporters could be given a special access. or a free tournament ticket they can use or give away to someone signing up

some Go organizations, or Book author might want to sponsor
