Need help with a bow...

I got a gold req 9 shadow bow. it has bad mods but those can be replaced. could some one please tell me if it's possible to upgrade it so it would worth a substantial amount of money? if it is, which mods should i use? i know it's not the most desireable skin but with proper mods that shouldn't matter much.
Please excuse if i posted this thread in the wrong place...

well i would say the skin is not worth the trouble.

i got myself a 15^50 req 9 shadow bow 20^19 armor with 29 HP and i cant sell it less than 5k ....
PPl just dont like the skin....
so no trouble of making it perfect....
