Provide a clear example of a similar job you have done in the past.
I have worked with fitness brand BODYISM, shooting their sports clothing on athletes, models and trainers. While this isn't exactly swimwear, I think this sounds like a comparable job as this was shooting on figure and in a studio setting. Can provide images on request.
Proposal:
Hi there,
Thank you for taking the time to consider my bid.
My photography and film work is all on figure using models or actors, so I am highly experienced in directing talent and have good working relationships with lifestyle and high fashion model agencies should you need any help with casting for you shoot.
I shoot both on location and in the studio, so I can helo advise on a number of possible studio spaces in London for the shoot and help you to negotiate a good rate whatever your budget.
My skills also extend to post-porduction and I can do advanced retouching and compositing should you want this as well.
I would be delighted to sit down with you and discuss your project in more detail, view samples of your products and any references you may have for the type of images you would like.
Thank you again for considering this bid and I look forward to hearing from you.
Best Regards,
Nicola Saint-Marc
