Erm, despite the complete lack of information I shall try.
Simplest answer would be make it yourself, you would be able to customise it and make it perfect for your needs.
Otherwise, you should be able to find a variety by doing a quick Google (other search engines are available) search.
Hi..The concept of guest blogging is to write a quality article for blog owners in return for them to post your article with url’s linking back to your site. It’s a great way to increase your own site’s exposure and traffic in addition to gaining a sought after high PR backlink. By writing articles for authority blogs that are relevant to your own site, Google should take notice of the relevance and give you a boost in the SERPs. Please search in Google or Bing surly you will get top list of guest blogging sites. There is so many results for list of blog sites. Any query pls ask.Thank you.
