Show website owners how their website could look if they used our product

We are looking for a developer that can work with us on multiple projects. We want to build a long term relationship for developing stand alone applications of our software. The project to start with: Start with a webform, ask for domain name ($domain), a sector ($sector) and display a submit button Sector can be: health, beauty, automotive, education, administration, other After the button is pressed the content of $domain is displayed on screen (just like it would if you type the domain name in the browser) but there is a X% transparent overlay that shows the content of this script: So the user sees his own website in the background and he sees a list of services that are bookable in the foreground. The list of services should be 420px wide. Screenshots will follow.
