Hi!
First of all congratulations for the huge start and following orders.
But, I realise the team is not working full time on the project as its a start up you have to work day and night throughout on the same idea and get the issues solved. Make sure the team is dedicated towards working on Idea and initially not running behind money for at least 2 years. If the motive of joining hands is just money you all need to reconsider working and get it placed for a better motive. Money will flow in automatically.

For getting funds you have to make a project plan and submit it to various VC's around who fund a start ups. You need to understand the way in which the VC funds and accordingly do the little bit of changes and then apply.

I am sure you will find a way.
