Heritage has an international clientele, but do not sell as many guns as the auctions that specialize in same. I had a recent experience with them, where a gun was incorrectly described and they did not disclose a non working lock on a hammer gun. You might try Montrose Auction in Georgia. Small auction house that sells guns and are somewhat close to you.
Of all the auction houses that sell a lot of guns, Rock Island seems to get the highest prices. But, if the guns are not graded or in good condition, they will go in a "Regional" sale and be lost in the high quantity sold and bring sub par prices.
James Julia, IMO, is for the super high grade rare guns, that will bring big money. I don't know if that will change with their recent merger with Morphy. Morphy puts out the nicest HARD BOUND catalogs in the industry.
There are other auction houses to choose from, Amouskeag, Little John's and Carol Watson in Ca. To name a few. Check with each to see what fees they charge and how they market.
Good Luck
