Hi there!
I'm Alessandro, an architect from Florence, Italy.
Of course I do know very well Photoscan, infact I use it quite often when I have to study old buildings and similar.
I can send you some examples of works I've done there if needed!
By the way the offer I've made is totally random as I don't know what you will require me to do.
Really looking forward to help you,
best regards,
Ale
