Unless you were on an integrated cadet scheme with an affiliated flight training provider, I think you may be setting your sights a little unrealistically.
Most airlines require applicants to have ATPL level basic experience (1500 hours) and around 500 hours of turbine experience as a minimum. There is nothing new in this, they always have done.
For cadets with less than this minimum level of experience, recruitment is normally in conjunction with one of the main training providers (Oxford, CTC or FTE.)
Most of the major airlines are type rating training organisations (TRTO's) and will provide type rating training where necessary to those suitably qualified and experienced applicants. Paying for a type rating isn't going to improve your chances much unless you also have commensurate levels of relevant experience to go with it.
Type rating a suitable applicant from scratch takes around 6 to 8 weeks. The applicant may (depending on the airline) be contracted to those training costs (bonded,) or may be required to pay those costs in advance. In any event, the airline can appraise and monitor the candidates progress.
Obviously somebody with 250 hours and a type rating they have paid for themselves, as part of collection of self acquired and unmonitored courses, isn't likely to excite the interest of many companies. There are no shortage of companies selling this type of stuff, and similarly there are companies happy to charge you to attend an interview. However for most people with 250 hours and a CPL/IR, I am afraid airline employment is not a likely proposition in the near term.
It isn't a break you need, it is a better and more realistic game plan. Having said that, it still isn't going to be easy. An instructor rating might well enable you to obtain employment that would if you were successful, keep your flying skills from becoming rusty. It also enables the logbook hours to keep clocking up. In adddition it would hopefully provide you with new teaching (and learning) skills, that would be of benefit in the future.
Somebody in this position would be at a significant advantage to somebody not flying at all. Both could still send out CV's to all and sundry, but the instructor would actually be working towards to the end goal.
