I want to build my own site for my business. Any advice?
You can build a mobile website very quickly (which you can use as a PC site if you want) through http://www.web2mobile.co - you will love this service.
your question is very general. Could you please specify what kind of website you would like to build?
Will you introduce your business in general and/or your products or services, do you want to sell products or services through the website, share relevant news etc.
Are you looking for free solutions or can you spend some money for hosting? Are you willing to hire a web designer?
We have had similar questions before, please have a look at them here:
