Acting as your own project manager

I recently finished a complete design for a client in Brainerd. He then supplied copies of the plan to five different landscape contractors and obtained quotes from each for the entire job. He wasn't pleased with the results so he decided to act as his own project managar. In doing so he found the nursery that had the plants at the best price. He then found the company that would do the irrigation system at the cheapest rate. Next he found the contractor willing to do all the earthwork and seeding at the best price. Finally he selected the landscape contractor with the cheapest rates to install the plants that he had purchased. By taking the time to do this he saved $7,500. I think this is a great example of how to save money on a large project.
