Since no-one else has bothered to answer you: no, you can not convert a NPO into a for-profit business (this is prohibited by Section 2(a) of Schedule 1 of the Companies Act).
With that out of the way ...
This is an understandable assumption but, in my experience, also a flawed one. There are thousands of NPOs, NGOs, charities, community projects, etc. competing for government funding and private donations. Furthermore, the process for applying for government funding is often long, frustrating, and administratively complex. Even if you are successful, registering and managing a NPO is highly regulated and administratively complex.
Honestly, it would probably be easier to start a for-profit business (a lack of funding and experience need not be restrictive if you apply lean startup fundamentals).
