It's surprising how sparse the pickings are for trans related services in Florida. I did some quick google searches and found very few doctors and therapists who specialize in transgender medicine.
However, I did find the name Sharon A. Thrush (Endocrinologist),2669 Forest Hill Boulevard, Suite 100, West Palm Beach, FL 33406. (561) 968-7600 Can't guarantee that the information is accurate, or that she prescribes medication for HRT by informed consent. I'll leave finding more information on that level up to you. A simple phone call should do the trick.
Remember, if a doctor is comfortable prescribing hormones under Informed Consent that physician will first ask a whole lot of questions, and she (or he) will expect honest answers. You may be asked to explain whether you have family, financial, or health care restrictions that effect your ability to access therapy and medical services. And you may also be asked to provide your prior medical records and tests. This would all be for your safety, and so it's best to supply the information if you can get it.
Here is a link to the University Of California, Medical Center, San Francisco (UCSF), web site for Transgender Health.
http://transhealth.ucsf.edu/trans?page=protocol-hormone-ready UCSF is a respected trans health provider in the San Francisco Bay Area, and when asked they routinely share information about how they treat and care for trans patients. Their web site is chocked full of information and as you review the document for Informed Consent you may want to review how they manage all aspects of trans health.
I now think we girls should always see a therapist to gage our ability to manage transition, and to asses our care needs. But I also understand how our individual issues sometimes critically interfere with our ability to proceed with transition in a traditional way. Gratefully WPATH Version 7 has addressed new non-traditional methods, and modified the standards of treatment to provide a greater level of care for our vastly diverse society.
Take care and I wish you well.
