Welcome to the forum.
For land like that, dig out as much of the roots of brambles as you can. I would treat the lot with a spray of glyphosate, as a one off to kill all the perennial weeds , of which you will have many. It will translocate down in to the roots and kill them off over a period of a few weeks. Then you can hire a rotavator and rotavate the lot. It is no good rotavating before you kill the perennial weeds as they will come back many fold. Then you can either plant it up, or cover with thick black plastic to keep it clear until you plant it next spring. I know it would be nice to have stuff in this year, but inadequate preparation of the ground this year will mean you are forking out things like bindweed,field thistle, docks etc for years to come.
