Develop a professional web site for me. It also should have a very efficient search box.
The people should can sign in and up and cookies have to be used, I think, because the website has to remember, on which things the user has clicked.
The website will sell things, so people have to be able to buy them without problems.
So you develop the website, and I decide later, what the website will sell.
If I do not like how the web page was made, I must not pay.
