Asked to build community page

[MightyMu]

Hi all,

This morning I was asked to build/manage a community fitness page based on a specific country. I myself have a bigger page in this niche, so I know how to build a page in this niche.

However, how much should I ask to build up a page to 10k and manage the growth afterwards. Should I ask a specific price per 10k followers?

Thanks in advance for the help!
