I building a Wordpress website and would like to include a live NSE feed preferably as a news ticker and if possible an additional display similar to the one on wazua (http://www.wazua.co.ke/investor/livefeedfull.aspx). 

Would appreciate:

i) Contacts of any such data vendors

ii) Your experience both positive and negative working with such data vendors

iii) Costs involved

iv) Any other relevant info on possible data vendors of this service
