Website user interface Design

Hello Designers, I need a skilled website interface designer to make the user interface for my website. You should be good with design tools like photoshop, and must also have html+css+javascript knowledge. Though I am going to ask you to make the photoshop design only, and not the final html work. I have a web based software, and I want someone who has experience with user interfaces. You should understand user experience, and should be able to give me suggestions on how to improve it for my user.
