Good afternoon. Often sites are created that are designed for a local audience, which is located in a certain place. What should I do to promote such sites? For example, I opened a site with CBD products in California, and I plan to work only with the Californian audience. What should I do?

Good afternoon. An acquaintance of mine needs help. He is interested in registering an LLC in Colorado. Are there people here who can help with this? How do I register an LLC in Colorado and what do I need?
