Can't speak for Poser but Daz3d has nice joint integration (click+drag) that makes it pretty easy to pose characters.

If you're just getting your feet wet, look around the torrent search engines for 'daz3d' and/or 'renderotica'. There are some 1-10gb torrents floating around that have huge archives of just about everything that's available publicly. Obviously buy the content if you're going to be setting up a patreon or something, but you shouldnt have to spend thousands of dollars tinkering around with side projects.
