The last thing I can afford to do is waste money
If I've read you correctly, you are talking about paying to hour-build to 1500 hours in the US? (I am concluding this from the bit where you say "The costs are considerably lower than gaining 1500 hours in European airspace".)
Why would you want to do this, especially if you don't want to waste money, when you can get a job either side of the Atlantic with around 250 hours? Ok, so it might not be the best-paid job in the world, but it will certainly pay you more than you'd get paid for hour-building.
