Hi Syed
Look through these forums, do a web-search and see what you come up with when looking for a decent good quality FTO that does the FI(A) Course.
Cheap shouldn't always come into the equation - high standards and good quality instruction should. There's the old saying you only get what you pay for.
A little investigation now could save you money in the longer term. Check out prices, and ensure that you know exactly what you're getting, or not getting, for that price. Are there any hidden extras etc.
Remember, how you are taught on the course is how you'll teach your future students. Sorry if this sounds like I'm teaching you to suck eggs, but it's realistic.
LASORS or the FTOs you find will tell you the requirements etc.
Good luck and happy hunting
Regards D 'n' H
