Weekly Marketing in Forums

I am looking for someone who will work weekly for our brand establishing a presence in an internet forum and then communicating directly with forum members who inquire about products that we offer.

Here is what I need in order to evaluate your offer:

1. List any forums you are already an active member of and familiar with.
2. Tell me any brands you market for in this manner already.
3. What is your hourly rate?
4. What is the minimum number of hours you're willing to work each week? For example, if I just want to hire you for one hour each week, can I, or what is your minimum?
5. What is the maximum number of hours you're willing to work each week?
