Hauling cargo in a Vette, here we have a man who likes to suffer.
But yeah, do that then. =) Just for your cargo run the profile doesn't need to be perfect. You can evade an interdiction with anything, even a Type 9.
Ah, I just saw again that you downloaded a profile and don't know how to install it. Well, neither do I, sorry. ^^ I've always configured my controls directly in game.
More importantly, you'll find that EDDB doesn't exist anymore. Most of the 3rd party functions are now wrapped into Inara. Here you can also go to find a good market for your merchandise:

Just punch in your current system and what you have to sell, then in the additional options you can set Min Landing Pad to Large, disable surface ports, and go. Keep an eye on the distance to station (the closer the better), and drop the stuff off in the closest viable system. Then you can continue with the fun bit.
A Sidey may be a bit too flimsy. ^^ If you're interested in combat, something like a Vulture or a Chieftain are excellent choices. I think nowadays the Krait MkII is lauded as the best multi-purpose mission runner, though personally I don't like it very much, and it'll actually be too expensive to outfit for your current piggybank status.
