Looking For A Mermaid To Swim In Pool During Party

It is a 40th birthday party for about 100 people in our back yard located in Danville, California. It is going to be on Saturday July 28th at 7:30 pm until ??. The theme is a "White Party", very hip and cool, DJ , Great bar set up, every one dressed in white attire, just fun., Our back yard is focused around our pool and we thought that a great element to the party would be to have a mermaid swimming in the pool. That`s where you come in.

Do you know of anyone in Northern California that does such a thing? Any help or referrals would be much appreciated.

Thanks in advance for your help.
