Best method to get a single ticket to Sept 22nd game for someone out of the country?

Hey everyone. Not sure if this is the best place to post this, but figured it's worth a shot. I'll be in Houston for work and have a free night on Friday September 22nd and want to buy a single ticket for the Astros game.
Any thoughts on the best way to do this? Any suggestions on some of the more desirable locations to try and find a seat? I can spend up to $100 USD or slightly more if that gets me into a better spot. I've contacted a few people on Craigslist but they want me to send them money up front via Venmo which I'm unable to do but offered Paypal and they went silent on me.

Thanks James
