I need an old shed removed, the ground prepped and a new shed installed

I need an old 3x2.5 metre tin shed removed and disposed from the corner of my yard. There are two big branches from an avocado tree on top of the old shed that will have to be cut and cleared away. Currently, the shed is 2 metres from the boundary on both sides. The old shed is sitting on a base of concrete blocks and wood. I need that base moved so that it is deeper in the corner) as close to the boundary as it can go. And I need a new base for the new shed because it's smaller. Then I need a new shed (this one --- ) assembled. There is a bit of rubbish around the current shed which will need to be moved to a skip to make room for a new one (the photo shows some stones, but we will remove those). The photo also shows branches of our avocado tree currently resting on the existing shed. Those will also be removed. For any extra cost in addition to what I'm paying for the labour (eg .disposal of the old shed), the tradie can invoice me additional costs (with receipt). The shed is metal, so the tradie might even get some money for that (which he or she can keep). No special skills are required here (like plumbing or electrical), and I do think it is about two days work, so I budgeting to pay about $400 dollars for the labour.
