Congratulations!!!
Sounds exciting!!
If you plan to sell outside of your own local market, hit the trade shows. Fancy food shows and restaurant shows serve as a great way to build a "network" of others in the business outside your local area.

But, as you walk around, you get to start conversations with people in the business. You could hand out business cards, get to meet and know people, but NO samples if you do not have a booth.
Restaurants are tricky. If barbecue is big in your area, everyone usually has their own treasured and loved sauce and rub formula already.
If your stuff is SPECTACULAR, you will find interest in places that are barbecue challenged. I have a few clients in NYC that are struggling to find that perfect rub & sauce, as we speak.
It is important that your production facilities and procedures are compliant with strict health codes, to sell into retail, or restaurants. It will not work for food products that are "homemade" or produced in an informal production environment.
