I am interested in creating a website featuring stock option prices
sorted and displayed in a proprietary format I've created.  In order
to accomplish this, I need access to real-time option prices (both ask
& bid) for the calls and puts of all major stocks currently trading in
the US.

My questions are:

1) Which companies, if any:
    a) license such real-time stock price information to individuals
    b) allow (or better yet, assist in) the manipulation of the
data into my own formatting?

2) How much can I expect to pay (annually) for such service/licensing?

Thanks!

There used to be a 15 minute delay in these prices and stock prices. 

And because it was in a bid and asked format with a market maker
declaring the price he/she would pay in a sea of traders or in a
desert.  A buyer/seller hopeing for a large volume trade was likely to
get a different price than a small volume.

You would also need real time pricing of the underlying security in
order for the options to make sense.

Transmission time delays are also a consideration.

Still the closer you can get to true pricing the better the market
works for everyone.
