Alteration of JWPLayer skin

Hello All, I would like to alter our default JWPLayer skin (or to develop a new skin if we have to) so that we can include a custom button on the player. Sample of what we have at the moment can be seen here [login to view URL] We already have the embed and share buttons there. What we like to have is a mail icon below those buttons so any one can contact us if they have any feedback while watching the video. When some one click on the mail button it should open up a subject/email/body fields on top video so viewer can submit his message to us. P.S Please only bid if you have designed custom JWPLayer skins before!
