Okay usually when one comes up with a new idea for something the expectation is that it will be stated clearly what problem this new idea will solve and how it will solve it.
Here is the list of potential tasks set for the WCA http://meta.wikimedia.org/wiki/Wikimedia_Chapters_Association/Tasks
Why do any of these need paid staff to complete them rather than volunteers? Why do they deserve paid staff any more than the dozens of other issues that we have that are at least equally important? In fact no paid staff is requested for any of the tasks set forth.
A lot of "facilitating and promoting said work and idea"s of volunteer is done by volunteers. And IMO should continue to be done by volunteers. So am not conflating the two.
With respect to "The law firm is supposed to look over contracts, documents and agreements of 40 other organizations" Only 21 have signed up. Where does the number 40 come from? And why do all these organizations need documents looked over more? We have managed to find free lawyers for both Wikimedia Canada and Wiki Project Med Foundation and we managed to incorporate both as volunteers.
With respect to "If you employ someone on a daily basis" This is the issue. I am not convinced we should employ someone on a daily basis for this work as it is presented. Wikipedia is not a fancy shiny project, we are not Google or Microsoft. We are a rag tag group of "amateurs" trying to do something amazing. We do not need shiny offices, in cities of global importance, we do not need to fly around the world with important titles.
So with respect to a budget I would consider in the range of $25,000 to me more appropriate. No actual office. No paid staff. Some funding to cover limited travel for volunteers interested in taking on this work. Collaboration taking place on meta. Efforts to improve meta. Some free google accounts. The use of skype for meeting (which is also free). Most work taking place virtually. The use of volunteers and google translate to translate stuff. This organization of volunteers acting as a consultant as I know my chapter is not looking for anyone to tell us what to do.
