I have some outstanding technology based business unique method business ideas?

I have an appointment with a venture capital firm in 3 weeks they are interested in some of my ideas, I havent shared the methods by which they work, but I have gave the the outcome of what it does and they are very interested for the uniqueness and the market value which is billions. What can I do to protect my ideas besides NDA, i dont have business plans or nothing like that just well established ideas.

1. its great to know that VCs are interesed in you but actually i myself am against VC and Angel funding. these people give you money when your company is almost nothing and in return take 5-50 % share. but when the actual potential of your company is unleashed it seems quite unhealthy to you to give away just 20% of your earning just because he gave of small ammount of money for statup. what i will suggest is that if you really feel that your idea is really going to work great and does not require a very huge investment arrange the startup capital by some loan from bank or riend or family of from anywhere but just dont give away share i your company. and once you are ready start your venture as soon as possibe. jump into the market. all the best!!!!
