Six of the engineers have a commodities market where goods can be sold to unlock high level upgrades. This works on profit, which is becoming a bit of a problem now that hundreds of CMDRs are visiting these engineers every day.
One of the best ways to make a quick trade profit is to trade rare goods. I have made a list of the rare goods that have the maximum profit (over 145ly) for each engineer. I've excluded rares over 180ly and stations with very long supercruise distances.
These tables have the jump distances to the engineer and the distance between the various rare goods sources.

edit - updated the route planners. Coordinates of Helvetitj corrected, plus a few new rare goods added.

Examples of how to use the tables:
Start at Sirius to get rares for Marco. It's 145ly to HIP 80364 to get some HIP Organophosphates. The closest system to HIP 80364 in the table is Rajukru at 50ly, to buy some multistoves. From Rajukru it's 126ly to Karetii. From Kareti it's 98ly to Ochoeng, then 97ly to Kamorin and from there 71ly to Nguna. Your ship might now be full, so it's 165ly back to Sirius.
That's a 752ly round trip, which an Asp could do in 25-30 jumps.
.
Start at Kuk for Selene.
145ly to CD-75 661
40ly to Baltah'Sine
69ly to Arouca
28ly to Any Na
52ly to Deuringas
158ly to Tanmark
18ly to Tarach Tor
29ly to Utgaroar
50ly to Coquim
130ly to Jotun
39ly to HIP 10175
128ly to Kachirigin
95 to Vanayequi
156 to return to Kuk
That's 1137ly for the lot. I'd probably break that into two shorter routes, returning from Deuringas.
Rares for Liz is a little too easy. Just doing the Lave cluster will fill some ships.
