A Ride to Nebraska from Denver, July 27th

Hello community! This might be a bit of a stretch but I thought I should give it a try. My brother Diego, who is visiting me from Argentina, and I, would love to bicycle tour across Nebraska starting at the end of July and we are having trouble organizing how to get to our initial spot (Valentine, Nebraska), about 6 hour drive from Denver. No bus or train can drop us there so I'm looking for a kind soul that may give us a ride there. I'll pay for all gas and a couple hundred on top for this huge favor. I have a bike rack available to take both bicycles as well. The date we are thinking is Wednesday July 27th. We can come back from Lincoln, by train, but unfortunately we can't get the initial spot figured out! If anyone can help me, I'd be sooo grateful. Or if you know someone that might, please send them my way.  A little bit of myself: I was born here, raised in Argentina and recently moved to Denver after crossing México and the us by bike (about 7k miles in two years). Thank you for reading! Pablo (I live in the Sloan's Lake area).
