I could tell you to just join TEST/Honey Badger Coalition, because we own a hefty portion of the Southwestern portion of the map, and we take just about anyone who puts in the time to make an application, but that would be propaganda.
I could also tell you that since TEST/HBC owns MORE SPACE THAN WE KNOW WHAT TO DO WITH you could probably base out of the Blood Raider NPC stations in Delve with relative ease. Since there isn't any fighting going on in Delve any more other than the occasional gate camp, you could live there rather easily without having to join a corp. When I was running lvl 4 missions I saw barely anyone aside from 1-3 occasional neutrals, and they were just running missions too, so they were too worried about losing their ship to try and do any pvp. I actually saw a guy in a PVE fit Cynabal that was scared I was going to gank him, and many lols were had.
Here, I even included a handy dandy map for you.
Or if you don't want to join TEST cause we're lame and bad at this game, then you could try to join one of the pirate corps basing out of the Phoenix constellation in Fountain's Serpentis Space. I'm pretty sure they're not noob friendly though, but I could be wrong.
If you just want to get into some T1 frigate pvp then look at Red vs Blue or Factional Warfare.
