I did the bed myself, with little help from my 10-year-old son and my wife, took us around 6 to 8 hours.
Bought bare essential tools based on your videos (like wheelbarrow(2), spade/shovel(2), digging fork(2) (couldn’t get the compost fork though here), rake(2)) and lots of compost, exhausting budget for this month, hence postponed enrolling to your course as of now 🙁
