I can provide any photoshop service, send me pm on what item you want to get photoshopped and I can give you my portfolio.
Giving portfolio in private is not a good choice, if you are shy of it then how you think the user whom you will show it will give you work ? And if its very good and you are proud of it then please post the link or images here so we can see. Not everyone has time to PM you every time.
