I think you may enjoy flying with us. We are a mostly industrial corp operating in NPC null. Although I realise your preference is in Delve specifically, if you are prepared to make a move you could do worse than getting in touch!
We are a mature, RL friendly corp and have members in UK, US and EU timezones. Our members engage in mining, industry, exploration, PI and PVE
We have access to good quality Null (without giving too much away, less than -0.5) and our alliance has members online in the area pretty much 24/7
If you want to know more then I posted a summary here:
Please feel free to mail me in game or join our public channel “Bootstrap Pub” if you have any questions or would like to discuss further
Many thanks
