Being the laborer yourself ties you to the everyday tasks. The sooner you get someone trained the better it is for you to keep growing your company. While you should stay in touch with the methods and techniques used to do the work, you should cross train always to eliminate the reliance upon any one individual (including yourself) in the event that person is not available (sick, injured, quit...)
There is a saying in business that I have adopted that speaks loud to an owner: You should be working on your business and not just in the business.
I had different helpers the first year but the 2nd year I started hiring people. Things were growing too fast to be the main work force and in doing so, I could not keep up with the demand we created.
A lot of development needed to happen especially in the corporate structure and marketing. Nothing came pre-assembled or templated well to our business model so we had to customize nearly everything to specifications we made. Each business can be like a fingerprint and that's the beauty of it, we can make it as unique as we like.
I met a gentleman a few years ago who told me that when he came full circle, he would like to go from being a big company to just him and a helper because he enjoyed the work and didn't want to separate from it. Each person is unique in their aspirations and it is up to you to grow it how you want but in the end, you have to be happy with what you create.
