Why not do it yourself or get cheap site?
I’ll just illustrate this with something we all know and love. Jewelry.
Why would you pay $10,000 for this:
But only $5 for this?
It’s what you get in the package. Lifetime warranty, services, expertise, and the prestige that comes with it.
Anonymous’ analogy to cars is pretty apt, but I wanted to add something else.
I think when people think of web development, they think of web design – the look and feel of a website. They are VERY different.
Web design, you could say that you can pay someone and have a much better-looking website, but that’d be the only difference.
But web development, if your website is more than just a simple site with text and contact information, it’s very important.
You can’t create a website like Google or Facebook on a free website builder because there’s a LOT of work that goes on behind the scenes. A lot of calculations, a lot of database work. A lot of decisions to make based on what the user input, who the user is, where the user is from, etc.
Hope that helps see the difference better!
