adult non-nude member site

I need a website basically like an adult website that allows allows members to view all the contents but allows non members to only view certain "preview" or tour pictures.. once inside the site thumbnail pictures with a small text box explaining the picture set will be needed.. then the member can click on the thumbnail and see more thumbnails which if they click on the thumbnail it becomes a bigger picture.. The site needs to be able to take payment for membership weekly and or monthly... etc. Should be very simple project but want it to look professional..
