I would say the number one benefit to website templates is that they‘re going to save you from having to wait for somebody else to get done with your website. You won‘t control don‘t you? Well website templates allow you to have a personal website set up within a few days after purchasing. All you would need is to select the platform you want and then choose templates that are going to suit it. Now compare this to trying to do everything yourself or hiring a professional web developer. It can take days before the product is even ready to get started.
When you hire a professional web developer to make a website for you, it is also going to cost way more money. There are low-priced developers, and then there are high-priced developers. But no matter what you are going to end up paying way more than what you expect. Each one comes with pros and cons. Low-priced website designers are not going to be that experienced, but that is why their prices are going to be so low. This does not mean that they do not have the skills; they just are not proven enough yet to warrant a high price.
