I assume you're referring to Jaques Station specifically - no missions there but there are a lot in the surrounding systems (and other stations in Colonia). I setup shop at Colonia Dream in Ratraii (good selection of ships, outfitting and missions).
The most lucrative are in fact passenger missions to the tourist beacons around Jaques Station. One jump, ~1000Ls SC, one scan, one jump back, 1.5 million CR. Nice work. Also there are assassinations, massacres, scan jobs, etc that are over 1 million CR.
