I can definately produce a design thats far better than any of the examples you shown, my design would be sent to you as a jpg stamped with sample to protect copying of the design, i will remove that stamp and send you psd for slicing when payment recieved. I can also produce a lovely flash header forthe site butthis would cost extra.
The design would be structured sothat it can be easly placed in oscommerce or zenCart. which would provide you with all the store functions you require and alot more.
