Humility pilot,
Please do some homework on Part FCL requirements for a 737 TR, or any TR for that matter.
Will your licensing authority recognise these logged hours in Bangladesh? Will you have to convert your licence in order to operate on the intended airline's AOC in their territory? Will the TR be recognised elsewhere?
Email the likes of CAE oxford who are listed as training partners, have they ever heard of them?
Even if it is legit, you pay and sign, and you will not see that money ever again even if the TR and hours become utterly useless too you.
Does 55,000 Euros even remotely sound like a 'good deal' to operate in a third world country and give MSG and them (the airline) free labour? It doesn't even sound like 55,000 Zimbabwean Dollars worth of value. The Bangladeshi labourers of the Middle East will be better off than you by the looks of things.
But at least you could pick up some nice pearls at a good price in Dhaka.
I know pprune tends to be a very bitter place where every dream is put on a downer, but really this does have warning bells about it.
