Research & find a food manufacturer that makes pies

Hello, please include the word British to be considered.
My wife’s company is located in Houston Texas USA. She owns a British grocery store. We are looking for a food manufacturing or also called food processing company that can make different types of British meat pies.
I have attached some pictures of another company that is doing something similar. Boomerangs started off making their own pies. Now they have a food manufacturer/ processor making and packaging their pies for them in bulk, they are now just the distributor. I need help locating a few companies that can request quotes from to make and create different meat pies.

Here are two companies that are doing this. If you can find their exact manufacturer they use I will give a bonus, doubling whatever we agree upon for your fee. Thank you.
