WHo does track design and layout?

I live in Northern Virgina and have to drive to far to ride on a track. I have decided to buy some property and build a race track. Who should I speak with about designing the track and developing a sight plan? I want to build this track at the I-81/I66 interchange so it will be convienient to the area and located on major roads. I believe I wil also layout a campground for stay overs.If you live in this area and would supprt the track please let me know.
Also, once established, how do you get the majors to come race at your track?

thanks,

Claybo
