How do you think I'll do on my first MMA fight?

I have 6 years of wrestling (150+ matches in high school and middle school), and 2 years of MMA training. However my MMA training is mostly submission grappling, and I have competed in 10 grappling tournaments (5 beginner, 5 intermediate). I have a lot of strength and stamina as well, but I am still not comfortable with stand up. My coaches and teammates say my hands have come a long way, but I have never sparred more than 70% intensity, and I am a bit nervous because of that. I am very comfortable with ground and pound and submissions, but my right cross is the only strike I land well. My kicks are very good, but my reactions, footwork, and head movement are very novice. What are the chances that I'll get beat by an 0-0 guy? I don't know anything about my opponent yet.
