First of all - accomodation tends to be quite expensive especially down south (me living oop north!). A touring caravan is a great way of having your own space and saving lots of money! I did it in fact the CFI did it also.
Secondly - Modular course is much cheaper, flying in the US is also much cheaper! I would advise buying 'The Guide to getting a Commercial Pilots Licence' by Clive Hughes.
Thirdly - "its work, oh its work but its great fun"......so I have been told
All the best,
