Hi, I am interested in your job offer, but I want you to know that I am not professional photographer. I have Nikon D5300 cam with 50-300 lens, so I am able to take pictures on distance (secretly). I just can't promise them to be a super professional, as for this better lens and cam is needed :)
If you won't be able to find a good candidate for your work you can always contact me as "plan B" and we can discuss everything, I can present some of my pictures which I made on distance, also you can see some in my profile (not in distance ofc)
I wish you a nice trip to Bercalona :D
