Good luck, but I think comparing prices with CTC isn't the only one to compare with - many students from the UK, when looking for a cheaper course, will consider FTE in Jerez. (ftejerez.com). As it is a) closer to home for European students b) has reasonable weather and c) has the "European ATC environment" that some people get so excited about (OK, it is useful for doing the IR), many will prefer this option unless you can really beat them on price or content.
