Some questions concerning the first three years.

Dear friends. I’m planning to apply for Tier 1 (Entrepreneur),
Could you help me please, I have some questions to ask concerning the first three years.

1. After I have registered the company, do I have to transfer 200k into the account of my company not later then 6 months?
2. How long do we have to employ two British people – within all three years or within the last 12 months?
3. If I haven’t spent all the amount of 200k within 3 years, but have spent only part of it and the remaining part is still on the account on the company is it acceptable? Sell I been given scores?

Probably these issues have been discussed, so please give the reference.
Thank you in advance.
