Normal DE's cannot test for an initial CFI, they are specially designated this authority by the local FSDO, Most of the initials done in Central FL are done at the FSDO. Be very careful if you are going to do the CFI-I as your initial ride, it is a lot to take on, at ORL FSDO you can expect an oral of about 8 hours just for the CFI, they will cut you no slack and you could be looking at an oral over two days if you add the Instrument. I whole heartedly agree about the MEI as an initial, this is what I did, and then did the SEL and I-I as an add on a week later. Good luck.
