I already had a ppl and did hours on my own. Then one provider for ATPL distance learning, and a single provider for CPL / IR / ME. I would suggest that you look at least at a single provider for the post hour building flight training (I.e CPL / IR and MEP), if for no other reason than its alot less hassle and you get a continuity of training. It is also alot easier to plan and is likely to be completed alot quicker.
