I need a business attorney familiar with insurance agency

I signed an independent contract with GEICO. It's a Maryland contract but my small insurance agency is located in Missouri. Per the contract, I do not own the book of business that offers renewals and has a 30 day opt out clause. I need to know with all of the business I've created in 16 years is there any retrubation if GEICO opts out for any reason leaving me with no future earnings as with most other insurance agencies. I realize that I know what I signed.
