You can also hit up your local chamber of commerce or specific business associations local to your area - they might not directly have a need for you but they are good networking tools. It sounds like you are trying to go big and the more local business people you know the better.
Do you have a website - it also sounds like you have enough services to justify having one (commissary, cart leasing) then have it listed on google (for example) so when someone is searching for what you offer they can find you. It is also easy to direct people to a site when they want more information and nowadays people almost expect you to have a website if you are a legit business.
Also I understand what Curbside was trying to say - with the clients you already have you should be working out all the bugs because there are sure to be issues that will come up. Better to solve them now than to grow to fast and have issues become major problems later. You don't have to pat yourself on the back, but you can take a deep breath and exhale slowly....
