Scott Collier: – (www.scottcollier.co.uk) this photographer is fab and offers a couple of great new services that will make your day even more spectacular.

How many cocktails is a good number: no more than 6, and I usually recommend 4. This is because of the pre-prep required, the effect too much choice can have on the quality of service and the number of ingredients you will need to pay for.

A mobile bar for a minimum of 100 people needs to be at least 4m in length otherwise service will be slow - and no-one likes to wait for their drink!
