Assemble & hang

Hello, Can you give me a quote please, for the following items & I will attach photos: 1. ● Assemble & attach 2 x storage units in my utility space, over washing machine & tumble dryer (see photo) ▪︎ one unit dimensions WxHxD 65cm W. 190cm H. 30cm D. ▪︎ Weight unsure 2. ● Assemble a bathroom tall storage unit. (see photo) ▪︎ Overall dimensions: 37 x 31.5 x 203 cm (L x W x H) ▪︎ Weight: 28.09 kg 3. ● Hang a large mirror at top of the stairs. (see photo) ▪︎ Dimensions: 60 x 149cm ▪︎ Weight: 9.83kg 4. ● Hang a small mirror behind a door. 40cm x 50cm 5. ● Hang 4 coat hooks on back of doors (2 x bedrooms, bathroom & utility) approx 45cm L The challenge however is that my walls are DRYWALL. So anchoring could be tricky with the heavy items, I'm thinking. You may not have any bother with this. I'm blue in the face from Snaptoggles and Easyfix hollow wall anchors for my TVs. Hope I attached the pictures correctly. Thank you.
