Small Tent/Marequee Hire Needed

Hello -

I am looking to have a New Year party in my back yard in London (nw6
6sh). We have a back lawn where I was hoping to erect a tent for 30 -
50 people, that would be heated and weather proof. Although there is a
Fence it may be better to look into a free standing structure. Just
Wondering what kind of price for various options you may have for me?
Please also include pick up/delivery costs also.

Thanks!

Jo
