Just tread lightly...750 hours is still just starting out in this career and if you let this option that will cost you 10 grand out of pocket it certainly will not be your last chance.
I say again, 10 grand is a TON of money to pay for a job. Hang in there, keep doing what you are doing to build some competitive times and you will get a lear job and the company will pay for it. Unless you are absurdly loaded I just cant support paying this kind of money for a job without some sort of guarantee from them, preferably long term.
With that being said, let us know where you decide to go to get your type and how it went.
