No, I have done everything myself from the very beginning, so there hasn't been any need for it.
I am very happy for any help! People that know more about mods and could help me with crashes I do not understand, and also test new updates are very much welcome. And yes, something very important: helping me with correcting/improving my grammar. I know it is far from perfect, even though I always try my best. Someone who know the language fluently would have been perfect. It would be a huge relief if I had only (or for the most part) the quests to worry about.
I do not have experience writing mods or debugging Minecraft crashes, but I have lots of Java experience so I can sift through the code and help where I can.
If you upload the source code to Bitbucket it will be private by default and you can invite collaborators to work on the project with you. (I prefer Github because of its elaborate code search, but it's not private by default) I'm running a server with your modpack so I can test changes both in a single player environment and in a multiplayer environment. But if you decide to go either Github or Bitbucket invite me: jacobbridges
