Furby, sorry for the late reply !
You are moving into a competitve world. Larger companies such as the one I work for are in a position to cater for small and large airlines alike, offering Web Based systems and virtual In-House systems for both Crew and Flight Planning. If you have the resources, you might want to consider a niche market that is not yet exploited.
There are a number of products out there, as I say, and you will be up against dozens of companies, though I would say there are about five top players.
