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.
Website templates are also extremely well coded. What does this mean to you? Well let‘s assume you do not know anything about coding. You are going to want to make small changes to the templates, but you may not know what you are doing. Learning how to make these minor changes will only take a few minutes in most cases. These templates are very well coded, usually with the most up-to-date coding methods. So you will never need to worry about this. Not to mention the fact that website templates are very search engine optimization friendly.
