How can I upload a word document to make a webpage, I need to send links to people in emails?

Word docs are not really web friendly. You could however, convert the word docs into PDF, and post it on website. U could use CutePDF (freeware) http://www.cutepdf.com/Products/CutePDF/writer.asp It is a virtual printer. So if you want the word into PDF, just print the word and select the CutePDF printer. Then you will have a "save as" dialog for pdf. I think the easiest way for coupons websites is to make a blog via wordpress. People are familiar with blogs, and PDF is web friendly, so what you need to do is to get a hosting with good customer service (to help you setting up the website) and your ok. Since you want a coupon based system, I'm not sure which hosting could be your help. But you could try providentHost.com. Their customer service for paid clients are very good, and they have video tutorials all across the control panels so you could try to learn and do stuff yourself (like installing scripts) if needed.

I create my coupon in Word then use cutepdf from http://cutepdf.com to create a pdf version. Upload pdf doc to the link location on my web host.
