"Media" is always a great keyword, and names containing it sell regularly. The value is typically dependant on the strength of the pairing word(s), the length of the name, and the number of sites/businesses branding themselves with the term in question.
"Peace" is a decent-not-great pairing word. It conveys a meaning, and it's short and easily spelled (although confusion with "piece" is a minor issue). On the down side, commercial usage options seem a bit limited, and from a subjective standpoint, it's not quite as edgy or memorable as I would want a Media name to be.
There are a few companies using similar terms:

However, none of the above seem like good potential buyers.
Resale value (i.e. looking for a quicker sale to an investor) - I would place in the $100 to $300 range.
End user value - I would say in the $1,500 to $4,500 range (but as with many names, you're likely looking at a long hold time).
