Hmm, finally found the solution.
Actually, friends, the reality is so much something, like if you listen then you may "wwooooh so is it"
Then listen to friends, Yes, it is true that there are lots of free websites builder software, but it is only free for sometimes not forever. I mean WordPress is also a free website builder software and there are lots of free themes, plugins with which you will be able to create your own website.
But I will tell you something about the free website, so read the following below.
1. Free themes and plugins may not work so well if you are trying to earn from the website, because some of the free themes may not build in SEO.
2. Your website may not be as exactly you are looking for, because it is already a ready-made.
3. Some of the plugins may not be suitable with your website, in that case, you are not able to install that plugin and without plugin your website is nothing.
4. Wordpress is open source and everyone knows the codes how to modify the WordPress and I had heard someone saying wordpress may be easy to hack.
Now let us talk about the website that was built by hiring developers.
1. Your website will work so well because the website will be as you are ordering.
2. You can draw a website design in a paper and send it to your developer, he can build the website the same as you had drawn.
3. You can add as many functions as you want on your website.
4. As the website is built by developers only you and developers know about your website and it may be strong in security.
So that it, I hope you had understood now.
