Iphone Graphics Header and a few Buttons

Hi, I have an iphone app that I would like new buttons for. I would like a longer term relationship where i can send smaller jobs to be done as needed on a weekly basis. I have a developer working hard on an app and the design needs updating. Attached is a sample. I would like the rest of the button done in the "gloss" format. This is for retina display/ipad. Please give me a price. When the job is complete, I would the like the PSD files. Also the buttons seperated individually. You have the format alreay as shown in the example. All there is to do is change the color of the headed and footers. There are four colors. That's it. This is a VERY simple job for experienced designer. I would like to see exaples from portofio also. The main inbox file is the old color and the cal-inbox-01 is the NEW.
