Hi Casi,
Ceramic Arts Daily might be helpful in finding some resources you need. They have blog posts and video archives of how to's, books, videos for sale etc. Not sure if you have to subscribe to either Ceramics Monthly or Pottery Making Illustrated to get full use but subscribing to Pottery Making Illustrated might be helpful to you as well. Lark Books also puts out some really nice "how to" books - I know tthey have at least one handbuilding book. They can be found on Amazon for sure or perhaps at your local clay supplier
http://ceramicartsdaily.org/Wish I could be more helpful, but I'm more of a thrower. I know some of my handbuilding friends press clay coils or slabs into plaster or other type molds to handbuild larger lighter pieces consistent in size. Maybe that could be something to try.
Good luck!
