I was recently achieved part of ambition (Nemesis) that other londoners call a Knifegate. And now I struggled to choose to get parabolan base camp or just grind honey from starving artist. What should I do and how should I make-money in this patch?

Get into new content (including parabola, lab, bone market and railroad). There are numerous options to make money with high efficiency (3.5 - 5 EpA).
