Hi,
I'm a US based social media marketing and advertising expert. Although your description is a little unclear, I think I have a general idea of what you are looking for. Typically I prefer to generate a marketing analysis and recommendations report, flat rate of $100, before committing fully to any projects so all parties share the same expectations. My average rate for complete management of content creation, paid advertising, and organic interactions is $1000 USD per month, however each company's social media management needs are different and I would be glad to chat with you in more detail about the specific requirements of your project.
Best regards,
William Bell
