Sorry, but there used to be a great article here about dealing with disgruntled customers but since Google penalizes web sites for using duplicate content I've removed the article.
Now I'm only using 100% original content on my Home Based Business Opportunities web site which is what I recommend that everyone else do also.
Many people think they can build web sites by buying thousands of articles or Adsense ready web sites for a one time price of $49.95. Sorry, but it just doesn't work like that on the web.
The person selling you those article has already made their money off of that content and now they are trying to get your money. And believe me the only person winning in a deal like this is the person selling this junk.
Don't do it, don't buy reprint articles from anyone. The only time you ever want to use articles on your site is by hiring authors that will write original content for you, that is specifically for you and you only.
That way you won't get ripped off from someone trying to sell you junk so they can get rich and then you turn out to be the disgruntled customer.
I have used Elance.com for hiring authors and have been very pleased with the quality and the timeliness of the work I have contracted out. It is easy to use and you can usually get articles written for between $5 to $7 each.
It works like a reverse of eBay. You post your project and authors bid on it. You then can award the project to anyone at any time. Of course you want to look for a low cost for your work, but you don't always want the lowest bid.
Beware of the really low bids in the range of $2 to $3 per article as they often come from people that may have poor English skills.
Only award work to people that can give you example of projects they have finished in the past. If you don't like what you read, don't hire them.
One hundred percent original content is the only way to go on your web site!
Using anything less and you will run the risk of getting your pages and possibly your whole web site not listed in Google.
And you certainly wouldn't want that to happen!
