Some key tips before you start is to limit your expectations. Understand that it can take at least a few years for you to finally start seeing things rolling in your business, where word of mouth begins to take over and attract potential customers for you. At this point, if you have the right systems in place, you can start growing your business with confidence. Invest in the tools and equipment you NEED to have, not the ones you want to have.
Identify that in your business and rent items that are too expensive for you. And make sure you create a budget for your business and that you charge what you should pay. More on all of this later in this post.
