Activity in Weld county, CO

My family owns Township 3 North, Range 61 West Section 18: S1/2NE1/4, SE 1/4NWH/4 (480 acres) as well as Township 4 North, Range 6 J West Section 33: W1/2, SE1/46 (120 acres). We just received a lease offer with a deadline to sign in 2 weeks. Is that typical? How can I encourage further interest from others?
