One site that can be helpful is the NCSA website. They have free site access, as well as a paid recruitment program that will make your videos for you and send out info to every college in the country if you are interested.
The free site access allows you to search for colleges in any state(s) and level of competition. You will have to sign up with their site to access more advanced tools.
You are able to contact any college through their tennis "portal" if you think you might like to attend that school. A coach should follow up with you.
The key is finding a college that needs you. A great deal of colleges have a women's tennis program!
If you want to play tennis in college, you should be able to find a home if you are open to the options available.
