There are very few organisations of any kind that will train unqualified people to fly their equipment. As you can imagine, there are many thousand of pilots worldwide with excellent qualifications (hours and type ratings) who are currently unemployed, so it's unlikely you'll find anyone to pay for your training.
I would suggest that you are going to have to get some kind of ICAO CPL, and some twin time, before you stand a realistic chance of getting your chosen job. This will cost you money! It is possible, however, that you may be able to get a licence, local to your potential country of employment, considerably cheaper than a JAA or FAA licence. Don't expect to be able to export your qualification elsewhere, though, until you have many thousands of hours.
For maximum employment potential, you should have a JAA or FAA ATPL. As you will know by reading this forum, these are going to cost you serious money. I'm sorry, there's no way round that just now. Ironically, it may be easier to get a jet airline job than what you want at the moment!
