Picture hanging in st albans, christchurch

We have one heavy mirror and 3/4 large artworks to hang in new build in St Albans. We move in 4th October, hoping for 6th or 7th October booking. One of the pictures is very large and heavy approx (1.5m x 1m)and will hang in garage. It is currently hanging on timber nailed into studs in garage. Two of the other artworks have no glass (1.2mx1.2m & 1m x 1.2m) , so not too heavy. Please provide approx quote. I would think the job would be an hour to 1 1/2 hours. I cannot book the 6th October? Due date : Tue, 9th Sep Location: St Albans, Christchurch Thanks
