I am one of the most highly regarded photographers on the UK's largest model casting website, and the most highly rated European photographer on this site. I also scout for a leading mainland Europe model agency.
My partner, who is not on this site in his own right, has worked extensively on London Fashion Week in the past, and is now returning to full time photography after recovering from heart surgery.
Your budget, however, is way off the mark for London work. This bid assumes both of us attending on each of the five days (we each charge $600 per day, and travel, parking, driving tolls and refreshments will be billed on top), and we will need you to provide official accreditation for us comfortably in advance of the event.
I know this is not the deal you wanted ... but this is London, and that does not come cheap. Please open a chat thread to discuss (but kindly note I am typically only at my desk between 0645 and 0800 GMT i.e. 0145 - 0300 EST and then again around about 1600 - 1700 GMT i.e. 1100 - 1200 EST)
I look forward to your message
Kind regards
Barney Douglas
PS your website was inaccessible in the UK when I tried a short while ago.
