Okay, first of all, as a disclaimer, my corp IS a nullsec corp, however I think I will be able to persuade you that we would be a good fit for you, so bear with me 
My corp is Mecha Enterprises Fleet, we’re the high SP USTZ corp and a founding member of the Federation Uprising alliance, a Nullsec/Lowsec PVP alliance based in Immensea as part of Legacy Coalition.
Now, here’s why I think you’d be a good fit for us, and I’ll try to dissuade you from the “Nullsec bad” at the end.

Edit : only 43m SP - even since 2006. When I say “on-and-off” player I mostly mean “off” as you can tell. Most of my skills are invested in Amarr weapons and armor systems.
Edit 2: I have an unhealthy obsession with Amarr. I need get that out in the open. Absolutions, Zealots, Harbingers, NOmens, Sacrilege’s, Devoters, etc.
We do fly a variety of subcap doctrines, and in terms of Amarr ships, Retributions/Pontifexex/Deacons, and Guardian logi are all highly used fleet types. In terms of non-Amarr stuff, there’s Jackdaws, Harpies, Eagles, Feroxes, Muninns, Ishtars, a large variety of stuff, but no matter what we’re flying, there’s always other things you can fly should you be unable to fly the mainline.
I enjoyed PVP but I’m sure I’ll have to relearn strategy again along with all the new equipment, balance changes, and ships that have come out over the years
We are entirely focused on PVP, and we are more than happy to help you relearn that side of the game.
Alright, and here’s the Nullsec part.
I don’t necessarily love nullsec life. I prefer lowsec if possible. Maybe things are different now.
My corp and many corps in our alliance has lived entirely in Lowsec for 9 years or more up until a year ago about, we live in Nullsec but we have a Lowsec mentality. The reason being is content for us has dried up in Lowsec and we’ve had to adapt lest we die due to a lack of content. We’re not carebears whatsoever, and in fact 25% of our kills are completely solo, and I’m an avid solo PVPer myself, especially in Lowsec.
