I don’t know about blessings, but I would create an effigy representing the entity that is your business, treat it as a “small god” as I call them, have an altar, or put it on your existing altar, and burn incense or light candles for it and feed it energy and intentions, talk to it about your planning and goals, use it’s name.
The object is to develop a spiritual and psychic connection with your business, so that you can work with it co-creatively and let it tell you what it needs to thrive.
This is based on the ideas in Michale Small Wrights works, and it has given me results where I work similarly with the spirits of the main software product I work with. I do this with the goal of gaining inspiration for creating solutions for my client’s challenges. Works like a charm
