I have a small business and a website now i want to market it through Internet. I have read little about SEO and PPC. I spoke to a few companies but they are charging beyond my capacity. Also i am not sure of their service. Can anyone suggest some good SEO consultant or affordable internet marketing company in India ( preferaly kolkata) ?
