Help with App Idea

Hi guys,
I’m trying to develop two apps:

  1. An errands and handyman app where people can place small jobs to be done and contractors or regular people can contact them and make proposals. At the beginning it will be a free app so no need to have any kind of payments, that we’ll add later.

  2. An app where people can login using social accounts, leave voice recorded questions and a group of experts could answer them in private or make them public so other users could listen to them. It could be like a professor with the students or a psychologist with patients. Also, need users to be allowed to vote, like or rank questions and answers.

Is it possible to do those with AppGyver? If yes, how?
I hope you guys get what I need, if not please ask me for more explanation.
Thanks and regards,
Carlos
