Blog plus Social Network and more

I would simply like you to prepare a short but informative report on the feasibility, cost, and software options for the project described below. You can structure the report as you see fit--I will use this report as a quick, initial roadmap to guide my decisions on how to proceed. To repeat, the project you are bidding on here is not to build the website for me, it is only to provide me with the actionable data that I am requesting below. Background: The website I have in mind will have the following features: 1) A Blog for which I will provide the new, daily content (mostly just text) 2) Social Network--a scalable platform for the site's community of users to post comments on the blog and communicate with each other 3) The ability for the site's administrator to take content (text, graphics) posted within the social platform and post it on the site proper (beside the blog, for example). 4) The ability for site members to vote and comment on content displayed on the site and for real-time (or daily) ranking to be generated 5) The completed site must be maintainable mostly by someone with only basic webmaster's knowledge. 6) Existing software (and/or SAAS) may be used 7) Both mobile and non mobile 8) Ads will be used to generate revenue for the site 9) A high level of polish is not required--but reliable functionality (especially regarding user voting) is required. 10) The total cost for creation of the initial working site must be low--polish and enhancements will come later At this point, I am not seeking a freelancer to build the site. Instead, all I want to get is an expert opinion of the feasibility of the project as described above, the approximate cost, and most importantly, which of the many existing social networking software/SAAS packages is most suitable for this project and why (including any sources you have for this info). A minimum one single page, bulleted document containing this specific info is what I am asking for here. Don't worry about literary merits of this document--I only need the info. If, in addition to this doc, you would like to provide reasons why you can be the one to build this site this project for me, that would be great too. Then at some point in the future when I feel I have collected sufficient info, I will proceed with this project and perhaps post another project accordingly. Please also include information about your background in your bid--or email it to me privately if you wish. Questions?...email me. Thx
