Pastor needs a good tent for his bike trip across Missouri

Hey everyone,
I need some help.  Throughout the week that I am biking across Missouri I am going to be camping at the end of each day.  The tent that I have is no good, as I found out during a thunderstorm on my trip across Kansas last year.  I was wondering if any of you have a waterproof and sturdy, two or three person tent that I could use June 21-26.  I just need something that I know will keep me dry.  If you have one I could stand up in that would be fantastic too.  The good ones I have found cost $200-$300. 
The other option I have is called Bubba's Pampered Pedallers.  It is a service that provides a tent, towel service, snacks and drinks, and a place to charge your phone and other electronics.  The trouble with this service is that it is $380 for the week, and I'm not going to spend that kind of money when I am doing this to raise money for Lead a Child. 
Anyways, if anyone has a good (proven to keep dry) tent and would be willing to lend it to me for the week that would be a tremendous help. 
Thank you!
