I’m sure it is possible to have that done. However, I think if you try by trial and error you can do it yourself.
I have a favorite "Texas Hot Dog Sauce" that I like as well. Actually, 2 slightly different sauces, one place closed some 30 years ago and one in my hometown that is still open. Both were closely guarded secrets. I did manage to obtain one recipe that claims to be from the place that is still open, however, I think it resembles the other place more.
I still make it and do a bit of "doctoring" of my own. Both restaurants were at one time open 24/7 and the one that is left hasn’t done that in years. Their sauce doesn’t taste the same either. So, I think a lot had to do with the fact that it was ALWAYS cooking.
What you really need to do is find a recipe that is "close" to what you want. Then do some "doctoring" to make it UNIQUELY YOURS and guard that recipe with your life. If it’s good they will come knocking your door down.
Just my 2 cents,
