How do I get more skins for my cellphone (Motorola W285)?

I want to get more skins that actually look good for my cellphone. The green is not my type and I dont want the purple skin forever. There are onl 3 colors and I want something new. I know you can get different skins for the Razr, but is there a download or something where I can get new skins or at leas different colored skins? And I don't want anything complicated, please. Thanks so much! <3
