WIKI SEO! Advisor to start set up new wikis, templates, categories, SEO.

I am starting 2 new wikis and want to do it right. You profoundly know wikimedia wiki usage and administration. Know both technical and common sense organisational issues. Advise with initial setup, settings, templates, categories, robots.txt. Wiki SEO is the main important! You explain how, and why, to best organize the wiki and give me links to sites that explain and justify your advice. Is it possible to integrate several wikis on the same server but on different domains? At least with mutual links. How to coordinate other participant wiki writers so they can maximally help but not screw up things. Legal aspects, copyright copyleft, Can a discussion board like disqus be integrated with a wiki? The wikis are very politically incorrect. If that disturbs you, we are a bad match. If political incorrectness interests you, that would be a plus and you might want to help further in the future. Confidentiality a must! Not necessary but a plus for helping with other projects: good knowledge of wordpress, FreeBSD Unix, regular expressions. This is a small non profit, so we try to do this economically. Because I can not give a clearly describe task, we have to discuss billing. We will start with a minimum amount but continue further on. Please explain how you can charge costs, on hourly basis, how you calculate your time. Explain what experience and knowledge you have for the tasks. How can we communicate? email, skype, whatsapp? I would prefer to give explanations and instructions as spoken messages on whatsapp. I do like low hourly wages. On the other hand, some freelancers grasp and solve things very quickly or find high quality solutions, and thus end up a good deal.
