Not quite sure what you mean? To meet Farseer you only have to do one thing, fly to Maia (takes 15 minutes in an empty T9) Land at Darnielle's progress, purchase a Meta alloy, pick up some of the long haul missions if you want to earn some extra cash, fly back to the bubble and deliver (you'll make around 30 million on average) Go to Farseer inc and give her the Meta alloy.
Can't really see what is hard about any of the above, as far as the materials & commodities for the upgrades, they can all be obtained through haulage missions inside the bubble. I got all of mine trucking from my usual spots in Aulis- I-bootis-Eranin-Ovid etc etc.
Now running LVL-4 FSD mods, and upgraded boosters. Took me about 5 days, Engineers went live during a really busy time for me real world, I had to steal an hour or so late night during the week to play. The longest part was getting Praseodymium, I took a mining mission (24 tonnes of Monohydrate Crystals) 4 units as a reward, turns out you can get the stuff just by doing any mission
