I feel I could do this project for you. I have plenty of experience in social media marketing. I have run tweet-Service for 3 years, which is a social media marketing company for small businesses.
I would work with you to come up with a social media marketing plan you want. But from what you wrote, I can do the social media posting for Twitter, Facebook and Google Plus for $80 per month.
I look forward to hearing from you to discuss your needs.
thanks!
Joe
