When are you going live?
It depends what you consider "live". The blockchain is live from the beginning and allowed trading BKS ever since.
Asset voting (to determine which tokens can be traded on the B&C Exchange) has just begun.
Trading the assets is still not possible, but that might change rapidly, now that Eleven has been hired as (additionaö) full time developer to increase the development speed.
Look at the progress here:

Funding is complete for now. If additional funding is required to develop e.g. a website to access the B&C Exchange blockchain, additional BKS might be created by the current BKS holders and sold/auctioned. This is not on the agenda I'm aware of.
How to fund?
Not possible at the moment. If you want to purchase BKS, you need to buy them on the open market, e.g. here:
https://www.ccedk.com/bks-us-nbt or via escrow. I can point you to someone if you are interested in the latter one (useful for bigger amounts than offered at CCEDK).
