Templete base website design can be helpfull to reduce the cost of project.
Templates can be the best option for a business on a tight budget. The key is to find the right template, with quality code, and actually do some good customization on it. Customization to fit the image of your business and to differentiate your design from the base design.
It’s a lot easier, cheaper and faster to do lots of customization on a template, than to design something from scratch.
If you have a decent budget, I would suggest you to get a custom design. But it makes much more sense to invest in a customized template and rather use the extra money you have on search engine optimization or some other form of marketing like google adword services.
