Kite-line.com was my first choice, I bought my helmet there, but they don't have any helmet to sell, unfortunately. The helmet is for a friend of mine, his brother-in-law will be going to Orlando soon, and is supposed to bring a helmet to him.
I'll pass your tips to him, one hour from Orlando is nothing, 40 to 50 km distance, isn't it?
By the way, we are having a great time here in Maceió, wind has been a good friend during the last 3 months! Should you decide to come here some day, the wind season is from the end of october until january. Just give me a call, 82-8863-8243! Long downwinds here, 100 km or more.
Abraço e se cuida!
I am also from Brasil and had recently been to Orlando. There are no shops there at all... at least, I couldn't find any after a long and boring search through the net. However, I've found a very nice shop in Cocoa Beach, which is like an hour or so by car from Orlando.
If you look for Ron Jon Surf Shop in Cocoa, you'll find it. On the net, their website is http://www.kiteboardingcloseouts.com/
There is another one, the 321 Kite, but, as they had moved, I could not find the new shop. http://www.321kiteboarding.com/
You can also look for gear online. I must say I like the Kite-Line store (http://www.kite-line.com/
