It sounds like your budget is somewhat limited. I don't know if you have engineers. If you do, here's a relatively affordable long range passenger Conda.
Good jump range, six first class cabins.
How to make good money with this would be to find a high population rich system of your choice (search and filter on eddb.io for extreme population high tech, industrial or agricultural). Booming is preferable and a handful of huge stations in the system. Go back and forth between those stations and pick up all long range exploration missions to a specific point. While you're filling up, pick up short range passenger delivery missions to neighbouring systems and check those for passengers to the same long range destination.
On a distance like Colonia, you'll make around 250-300 million cr on the passengers alone. Plus 50-100 million, easy, on cartograhpy.
It's good money for an extremely low risk job, and you'll most likely unlock the Elite passport to Jameson's Memorial when you get back home.
