My recommendation would be to find a flight school and go for it,
Then
Stipulate grade 1 instructors or at least a minimum of grade 2 for your commercial, flying with grade 3's will be a waste of your time and money at this stage of your flying.
Team up with another instructor candidate for the mutual portion of your instructor rating this will lower the cost.
Have a plan to do your instrument rating, you will need to do it eventually and it's hard (dam near impossible) to save up the coin for that on a pilots wage.
