Our Ideal Client

Our clients typically are referrals from our vast referral network of past clients, business, and social contacts. They value character, ethics, and truthfulness. They tend to be value oriented not price oriented. They know that a cheap price is NOT the lowest cost, so they are not scurrying around getting multiple bids to take the cheapest one. They respect our time. They recognize the value of time and don’t want to waste ours as well as theirs. They respect the fact that managing a job well is a skill set. Few can do it well. They generally have high but realistic expectations. They are generally decisive decision makers. They will do their research and want information. Once they have their information, they will make a decision, and stick to it. They have a win-win mind set. They seek ways to work with us to get the best value for their hard-earned dollars. They understand that we are a business and need to cover our overhead, supervise their project, and make a fair profit. If you feel you would be an ideal client, please contact us.
