My PPC Campaign Conversions is very low. How can I improve it better?

I am managing two PPC campaigns right now with budgets of 9000 GBP and 3600 GBP. I have optimised my PPC campaign with the good collection of keyword list powered by the fair adgroups and adcopies. I have also goods quality score in an average but I’m getting very less conversions per day say 1 or sometimes 0 conversions. I also read and followed most of the instructions given in the one of the articles published by sitepoint.com at the URL http://www.sitepoint.com/worst-adwords-campaign-mistakes/ also I have referred various sources to optimise my campaigns better. Although, I am getting very few conversions per month say less than 25. I feel that getting single conversion or less per day for this budget is not worth. Therefore, I would like to know other techniques if any which is not given in the article URL to improve my PPC campaign conversions.

Can you give an example of your ad copy and the url for the corresponding landing page as well as a few of your competitors?
