I will give you 3 quick points : 1) target NRIs and their tax questions. You will not find any more eager paying customers than NRIs who can get help with their taxes and also help in filing . Search the forums and you will will hundreds of queries and questions . Leverage those to come with a custom product offering for them 2) Get some Branding : you will need some solid reputation or word of mouth for people to come to you. Explore tie ups. 3) Get some white hackers to test your site. There is nothing more important than convincing people that they can trust you with important financial data. Have your sites "worked on" thoroughly. :-)

I can give more but not for free ;-)
