Joomla project - add modules and make it work

OK, so this project is to build an artist portal - but to speed things up and possibly cheaper i want it to be built from joomla. Once the community builder is in place there are only a few other things that are required; 1. Jobs section - i want to manage job postings (i want to charge money for them as well) 2. Each profile (artist) has their own personal picture gallery, contact and personal information on their page that they can update themselves, 3. A way for registered users to post events in an events section / also guests but to specify clearly that they are guests. 4. Article directory. People can post articles, they must be reviewed by the admin before they are made active and the admin can create categories for them to be placed in - also allow for pagination so that the articles can be split up into many pages (no scrolling). 5. New jobs, new pictures, latest members, latest articles all on the front page - possibly other stuff like forum integration? 6. When a artist registers i want them to choose a category that the admin can define - also a good search engine for type of media and name. 7. pricing - i want to define pricing plans so that i can make it free to begin and then add a pricing plan later on - even have many pricing plans depending on the amount of images they can upload.
