Why do you choose to buy from someone? There are many things you think about when you want to buy something, but when it comes to spending money how do you decide?
When someone is looking at buying a product, they might buy the cheapest because their needs are small or the most expensive because they are specific. However, when people buy services they want to hire an expert, not generalists. An expert has a deep understanding of a topic. When you work with them you can ask detailed questions and know you are getting correct answers.
