We frequently have potential clients and others say ,"I could just build my own website". The answer is, yes you can with a few major caveats.  There are a plethora of self serve website builders on the market that give non-designers/developers the ability to create a website. But it's like painting, building a home, or anything else you're not experienced with.  It takes many, many hours of practice to create anything decent. So if you're willing to invest a couple hundred hours learning it is possible to create a decent website.
