Extended Family Picnic Photographs (Wimbledon)

We will be having a picnic in the grounds of Cannizaro Park in Wimbledon at noon this coming Tuesday (July 11th). It will be 7 adults and 4 children. We were going to take photos ourselves but then a friend suggested we post here. We'd love someone to join us for 90 minutes to take photos of us a group and capture the picnic. No need for post work on the images. At the end of the shoot, we'd like to download all the raw images onto our computer. Thanks in advance.
