The main issue from a curricular standpoint is that Florida public schools do not appear to have very math intensive economics courses or majors. UF’s intermediate economics courses only require “survey of calculus” as a math prerequisite. It appears that other Florida publics like FSU, UCF, USF, FAMU, etc. do not require any calculus. PhD study in economics is very math intensive, so undergraduate preparation would involve choosing the most math-intensive economics courses (the most math intensive intermediate economics courses at some schools require calculus 3 and/or linear algebra as math prerequisites), and taking substantial advanced math and statistics courses (e.g. real analysis, proof-based linear algebra, calculus-based probability theory).
Look in the catalog descriptions for the intermediate microeconomics courses at the various schools to get an idea of how math-intensive they are at each school. Some schools offer more than one option, with more or less math (although some schools’ “less math” options require higher math than some other schools’ “more math” options).
That said, if your parents do not want to tell you about their financial matters, have them run the net price calculator on several schools that you suggest, so that you can get an idea of what is or is not likely to be affordable. Remember that you cannot borrow more than $5,500 (frosh) to $7,500 (junior/senior) per year without a co-signer (and co-signed student loans are generally not a good idea).
