I am the founder/CEO of a company dealing with services like data analysis and business planning. We can pay on percentage basis or project basis. One business plan of Rs. 20,000 would fetch you Rs. 1,000, for instance; and one big data analysis project of Rs. 100,000 would fetch Rs.4,000 on completion. For smaller projects, we can pay even 8-10% (such as hourly consultation for 4 hrs at Rs. 1,200 per hour would fetch you Rs. 400). With a volume of around Rs. 500,000 per month, you can easily get 20,000 - 50,000.
