I'm looking forward to starting my 1st hardscape job in a few weeks once the weather breaks. A family member is hiring me to demo a dry stacked slate foundation garden bed (about 6-8" high) and replace it with retaining wall block 3 courses high. In total it's about a 75' run with some curves. Being solo I'm not sure how long it's going to take to complete but I'll be keeping detailed records of my time to keep on had for quoting future jobs. I like the idea of getting into small hardscape jobs to extend the portfolio. I have garden design and installation experience but never messed with laying pavers or building retaining walls. Any tips from the pros?
