In using the services of an agent to find angel investors, what is a reasonable commission to offer an agent?

I am looking to raise First Round angel funding of US$1.5M in exchange for 40% of a company that is going to be based in India and produce an innovative product (for which R&D and consumer testing has been completed) to break a global monopoly in a US$ 4 billion high end market?
