So you are looking for a VA? Good internet is good and so is the fast computer, but most importantly you need an current version of FS
If you do not wish to fly online, there are VAs that cater for that as well. I suggest taking a look at a.net VA which is not officially related to this site, but many of the staff are members here (hence it was how the name was started). They fly a wide variety of routes worldwide with many aircraft.
You can find them at www.flyingcolours.tk
