Totally new and wanting ongoing advice.

Hey jayg, patience of a saint! I'll be more than happy if I can get cracking on the 2nd of January....want to get everything in its place and perfect so I can concentrate on growing instead of growing and clearing and building etc.

All different approaches already suggested. You may have the patience of a saint,but surely you got an allotment to grow on & unless you've got the worst plot in the world, you must want to get growing. If you do as you suggested in your original post you will end up needing to re start the process again on January 2nd. I admire you for wanting the perfect plot but as a gardener of over 30 years that is never going to happen,sorry.
