I think you bring up a good point/goal for discussion and I think you are on the right path. It is my dream too!
Most small of us business owners think too small. Too many of us work in our business and not on our business. I think the goal of any business owner is to create an organization that can run on its own whether I go away for a month or die, i want the business to function without me. Customers should love doing business with your company, not just doing business with just you. A business that has a great organization that can run into perpetuity should be the goal. I have spent 20 years trying to figure it out and haven't succeeded but mostly due to capital/income constraints and fear of stepping away. I am facing these thoughts as I get closer to retirement. Do I sell, do a merger or hire someone to run it? If we sell, and we are lucky, we'll get 2-3x cash to owner. If you and the relationship you have with your customers is the business, it is worthless to a new buyer. If you find someone who can manage and grow the business, you could get a paycheck indefinitely and still have an asset that is hopefully growing. I am considering taking on an equity partner to groom to take over or merging with someone who has younger leadership and a complimentary business. If I hire someone, I'd look for a "buy in" and give equity and profit sharing to make sure they are incentivized to stick around. I could use the buy in or the cost savings of combining businesses to off set the salary cost and not break the bank for a salary. Merging would bring in more business and more customers which would offset the extra cost of hiring someone. Either way, I feel like if you expect to have someone to act in the best interest of the owner, they need equity and a share of the profits. Look at large companies. The C suite has huge amounts of stock and large incentives to grow the company.
If you want to have multiple locations for sales or customer convenience, open up smaller centers for on boarding of customer and jobs and centralize production to one facility. For example, each location may have a roll printer and vinyl cutter for quick turn or simple products, but the main facility has flatbed, routers/cutters and generally equipment for higher volume or high skilled products. This maximizes your exposure to potential customers, reduces overall space cost, consolidates inventory and increases efficiency through economies of scale.
I remember when I got into this, I was told to run your business like you want to franchise it. Have great systems and processes that could easily be replicated or handed over on your exit. This is what helps a business function independently of ANY individual.
