Help. I am selling the Ultimate Tennis Compound

I am a Realtor in Texas selling an amazing 40 acre compound with a flowing creek just outside San Antonio in the beautiful Texas Hill Country. The owners' child is one of the top ranked juniors in the U.S. So, they have a wonderful lighted regular surface court and an INDOOR Tennis Center with both a regular surface and a clay court. This 150' x 120' facility also has a state of the art workout room. It's an amazing structure. I have a lot of experience marketing large estates but I think here I need to reach the tennis crowd. Price: $4.4 million. Any ideas?
