Download an open source or paid dating script. A script is a basic template for a certain type of software. For example, the Linux kernel is a template that allows users to build and modify their own Linux operating system. Whether you choose a paid or open source (free) script is up to you; however, a paid script is more likely to be user friendly and easy to understand, while an open source script is more likely to be flexible. Examples of scripts include SkaDate (paid) and osDate (open source).
Plan the visual layout of the site and the features the site will offer. Draw the main page and all other pages out on paper before designing them in photoshop or the image editor that comes with your script. This will require that you have decided on the features that your site will offer, so make a list of these features. Common features offered by dating sites include payment options, member search pages, profile editing, photo uploading, chat, instant messaging and email.
Design the visual components of the website software. Your script will come with some pre-packaged images, but you might want to design some on your own with Photoshop and a digital camera.

Open the script for every feature that you want to include on your site. Most scripts contain code for all conventional dating site features, so modifying the script to your specifications is just a matter of locating the sections of code that correspond to text and images and replace the pre-existing template with the images and text you want.
