If you have a company registered and operating and you only want to get your name out there the easiest way is to prepare a flyer and distribute it.
There are marketing companies out there like for example eflyermarketing.com that distributes your flyer for a super low cost (like approx $40) to 20,000 real estate agents in Miami Dade and Broward counties. Or any county you want. Contact me directly if you need any further assistance, my email is firstname.lastname@example.org. Good luck!
