This will be my first time performing landscape for flower bed. Property owner would like to replace current plastic edge with bricks. Attached is a picture of the flower bed and the two type of brick (undecided which she wants to use) The total measurement is 26 7. Need help in determining the labor hours it would take a professional to accomplish this task with just one person. I dont want to charge them more than what it would normally cost for labor since I will be going slowly to ensure I do a thorough job. A step by step procedure would also be appreciated.
