Why are you looking to do it yourself? if is because of the price restriction that most businesses get from web designers, I would like to offer you our services at www.Unthink.me - we offer web design on monthly payments.
Now, to answer your question there are many places where depending on your need of the website meaning that if you are not looking to complete online sales or sell goods, you might be ok with an information only website that may look outdated or all text just to prove your existence - then you can use pretty much a website building tool that most web hosting and domain providers offer. If you are going to depend on web sales you need to have a website that is not only well built on the back end and comply with search engines needs but also have items and content that speak directly to the visitors and convert them into customers.
