Internal Refurbishment

We have a single garage. I want it cleared out (if you have a large van to take away all the bits (I can send you a WhatsApp video of the contents). Then... The floor of the garage is sloping slightly. I do not want it levelled, I just want it flattened, so we can lay LVT on the floor. So, I'd like some liquid DPM, then expert self-levelling, using a laser. Then we want LVT to be installed. The garage is 8.5 sqm. Then there is another internal room where the floor needs to be self-levelled and installation of wood flooring. This room is 17 sqm. I need a small archway internally that I'd like blocked up with concrete blocks. I also need 3 doors to be hung floorboards checked.
