Im a young guy, however I really want to know how I will look like in 30 or more years.

On TV (in the UK) there is a show where they show a person now, and their forecast of how the person will look like in 30 years. They use these cosmetic specialist, etc.

On one of their shows.. they proved that their forecasts are very accurate when they gave a picture of a person 30 years ago to a specialist (he had to idea what the person looked today). He then made a picture of what the person would look today. They then brought the actual person out, and saw that the picture that he created was incredibly similar to what the person actually looked like today (it looked a little worse that she did.. but still very shockingly similar).

The show is on the sunshine news time (it doesn't actually have a show name, since was part of the news documentary).

DOES ANYONE HERE KNOW WHERE I CAN HIRE AN AGENCY/PERSON TO CREATE A PREDICTION OF WHAT ILL LOOK LIKE IN 30-40 (or more) YEARS?

Apparently there are not only companies who will do it for you, but software to do it yourself:

Thanks.. I didn't know that it was called "photo age progression".. thanks a lot :)

Well, it's called "age progression"... I just threw Photo in there to try to filter out general articles about the subject.
