I need a Wix professional, for an urgent, quick turnover project

The board is to be used for research purposes and will only be online for about 2-3 weeks and then taken offline for analysis. Members will be invited through email- its a closed group. Some basic requirements we need: 1. Participant log-in- closed private group 2. Segmentation into groups- so members can only contribute to discussions in their own groups 3. Participant profile- name, institution, country,(personal statement in about section)- this is a built in function in Wix sites that can be adapted 4. Back-end analytics (as indicators for steering team) 5. Discussion thread- main forum 6. Blogs to post (unidirectional communication from us to members)- stakeholder map, protocol, task list for general members, communication rules/netiquette 7. Control- assign roles to moderators, co-leads etc 8. Contact Tab- email link or chat function for troubleshooting, content-related and grievance- direct to us or advisory board 9. Badges- to mark minimum task completion, active participation, helpful team member etc 10. Host on our domain site.
