This sounds like an interesting task, and it is definitely along the lines of what I do. I would need more specifics, but I will be happy to stay in constant communication with you, keep you abreast of my findings, and continue to modify and adjust as you tell me exactly what you are looking for.
I can look on a facebook page, and see what they see objectively and subjectively. It sounds like you're looking for a facebook consultant like me to get many tweaks done. I would be willing to continue to work with you as you need me. Let's discuss more in private message, so I can understand your specifics. (I put in 7 days meaning I will start immediately, and we can continue to work on your project daily for a week, or longer if needed)
