A website designed/built that serves as a blog.

The website needs to be designed/built with a combination of both of our ideas. I have a good idea of how i would like the website to look however i do not have the required skill to build it myself. The website will serve as a blog that will enable the audience to interact with each other and the writers of the blogs. Also they must be able to create an account or log in using other social media sites. I have multiple websites i would like to build over the next 12 months with good work being rewarded with more paid work.
