I owned my own business for twenty years. Owned the building, large retail/hardware nursery, landscaping, repair etc. Lots of inventory and equipment. Here’s a few points to ponder.
Financing is one of the most important parts to stay afloat. No bank is going to finance anything without collateral. They will steer you to sba because their exposure will be limited. So expect them to put a second on your home. Looks like you need a working capital loan with a line of credit. The issue they will have is you don’t own the inventory that is why they will collateral anything you have equity in.
sba used to have a nice express package that I used for an additional line of credit. Stay away from online lenders or credit card financiers. You probably won’t have receivables so factoring is not an option.
2. Look for ways to generate additional revenue either add on fees or recurring. If you are doing car ports. Charge for set up and delv. Build into price. Maybe get into tent rentals etc.
Best advice I ever received was from a long time owner who told me. Don’t care the size of your business, cash flow is king. Follow that rule and you will be fine.
lastly. Have an exit plan even if it’s 20 years from now. I subdivided my property and sold off parcels. One to a credit union and the rest to a developer when a grocery chain built adjacent to me.
It is a great ride.. enjoy and good luck
