If you are anxious to get your trance site off the ground, you may just want to choose to download a trance template and get going right away! This is just fine: but keep in mind that not all trance templates are created equal, so here are some tips to help you choose the right trance template the first time and avoid regret later.
-- Choose the template maker carefully: there are plenty of fly-by-night operations out there that offer "free" templates that are either not free at all or are pretty lousy. Go with one of the bigger names out there such as Joomla or Dreamweaver and you will be guaranteed to be getting high quality and support.
-- Download your trance template from a company that offers plugins if you want to make adjustments later. Never say never when it comes to designing your page: you just may want to add a slide show carousel feature later or that scrolling text you saw somewhere else and really liked. Using a static template that cannot be modified over time is not showing foresight: choose a company from whom you can purchase a wide variety of plugins later to keep your site looking just the way you want it to.
-- Don't go for busy. No matter how attractive that trance template with the busy background looks when you download it, once you fill it with content the background will be a distraction. The background and content will be in constant competition for the attention of your site's visitors and they will eventually just give up and go elsewhere where the content is clearer and the format is simpler.
