At Jones you will train for the SES Rating in a Side By Side Cessna 180, while at Browns, you will be in a Tandem Seating J-3. Both put out a lot of seaplane pilots.
If you live in Florida, there is a company out of Wiconsin that has seaplanes that they both train pilots in, but also are willing to rent solo, with a reasonable about of dual time in make and model and an insurance option. They also operate in Florida. One way to both get the rating and build time as there are not many places that rent solo. There are:http://www.adventureseaplanes.com/
I have seen ads for reduced rate cross country time, twice a year when they move some of the equipment back and forth between their two locations, which is a way to gain the required make and model time at a reduced rate.
