Missions are good for people in the Edge World Areas, namely the Omicron systems, since the NPC's are powerful, the contract completion fee is very high at times. I've had to take down one fighter for a cool 900k once in Delta. I loved my Supernova when I got that shot off.
However, if your not in the Omicron systems, like most lawfuls, funding can become a major issue unless you rely on a trader character in reserve. I suggest boosting prices at Capitals, Border Station and Prison stations. Capitals have all them nasty loan sharks and angry politicians. Border Station patrols can be overstretched, and need any and all help. Prison stations want their prisoners back, so quell any hopeful captives on board given hope from a fellow escapee/police killer on the outside.
Mining, if we are going to boost the prices there, then the commodities on ALL station, bases and planets will need a revamp, like real economy, one commodity change will affect another. While miners/sellers will love the new prices, buyers and some companies may not like them.
RP wise for example Planetform Inc will hate the higher prices of silver for their cloud seeding projects.
But in the end, I'd like to see a boost in mineable commodities.
