eCommerce website in PHP

We have a potential prospect desiring a website and a budget estimate is needed for the development as follows: The owner is an artist and wants to display the paintings to the best effects. Also it is necessary to be able to change paintings from time to time so that may be a case for temples. An additional requirement is the site must be constructed so it can easily be modified. It is preferred the site be programmed using Macromedia Dreamweaver. The site will require a PayPal Shopping Cart. It appears the sample sites mentioned were constructed using Macromedia Dreamweaver and some templates. Following are some of our client's comments: ---------------------------------------------------------------------- These are the samples suggested: [login to view URL] [login to view URL] I've spent hours looking for a good website example that will convey to you what I have in mind for my website.

However, I have no clue about technology – so I will depend on you to tell me when I am slowing down load time.....or causing other problems! WHAT I LIKE: [login to view URL] on tone wallpaper background with decorative COLOR ART overlay on home page, and continuation of background gradation on buttons, in unobtrusive but interesting, etc. [login to view URL] button layout -I like that the buttons are always visible. It is easy to move around website.
