We are in the exact same situation you find yourself in; we are a returning corporation to the game (small-scale - 20 members total of which 5-10 play on a more active basis) and we are currently situated in high-sec space (0.5). Luckily we are close to low-sec in case we want to venture out that way.
PvE mission running (Ratting) and high-sec mining is our primary focus at this point in time.
