We may be able to help you with this. I am based at Potomac Airfield in Fort Washington, Maryland. It's about 10 minutes outside the beltway below National Harbor.
Email is the best way to reach me.
My range is about a 250 mile radius around Houston, Texas. Roughly that would include any field within an arc from Houma, LA (KHUM) to Monroe, LA (KMLU) to Paris, TX (KPRX) to Brady, TX (KBBD) to Carrizo Springs, TX (KCZT) to Brownsville, TX (KBRO).
