Sounds like a good price, hard to go wrong and worth taking a gamble on in my opinion. When I was running an engineering company years ago in a small mining town my company sponsored the golf club by buying all the glasses for the bar. We had our logo put on them. They got replaced as needed each year and it wasn't cheap, from memory it was a few thousand. We also contributed to the pot for the annual tournament. Didn't win us any work directly, but all our work was B2B and the management at the places that were our customers played on the course so it paid.
A lot of business gets done on golf courses, depending on the course and who the clients are. If it's a high end course and the players are company owners then there's a good chance to pickup some commercial work that way. It's a dirty world though, a lot of those guys are happy to award you contracts in return for money in pockets or getting work done at their own houses for free etc....
