Finally I am in a position where I can start flying

After initial concerns over eyesight it seems I am fit to pass a Class 1
So my quetion is this:
Is it important/easier/cheeper/better to do a PPL ((h) in my case) and a CPL with the same people?
The reason being there is a school that does PPL close(ish) to me but they do not do CPL training.
Any thoughts would be gratefully appreciated.
Many thanks
Dan
