I'm about to bid a job installing approximately 450 sq ft. of beds. Since mowing customers have been so cost conscious I have needed to expand my business to landscaping for which I am uneperienced but able. What are the steps I need to take. 1. mark out beds 2. cut edges 3. strip sod 4. add topsoil (how much?) 5. plant shrubs, etc. 6. add mulch Does this sound like it? Any advice is appreciated!
