With all the money that you will spend on a modular I'd recommend just going the full integrated route. Might be about 10K more but you can go commercial straight away rather than having to instruct.
I'd go to somewhere like Cabair if I were you - don't bother with oxford, they'd probably try to flog you the airline prep course, great - they guarantee an interview with a phantom airline they think they are affiliated with (those days are gone I'm afraid). CCAT have guys going to airlines now and I'd recommend it highly, best value for money I think.
