Hello! I need a little help. I've ran a janitorial business for the past 3 years and because I was trying to help someone I recently am trying to start a power washing business. I need a little help with the type of equipment to get is psi or hp the most important when it comes to pressure washers. I've recently went to Home Depot and found a pressure washer on wheels with a Honda engine that is 5.0hp with 2600psi is this enough for a pressure washing business? Do you have any suggestions for literature of estimating or pricing projects? Any suggestions of affordable places to fill a water tank?
