Professional “rough” sketches (originals)

I’m looking for three original pieces of art, in the style of the attached images.

A sort of “rough sketch”, in ink, with a medium weight, black pen on professional artist paper - perhaps cotton or wood pulp sort of stuff (open to suggestions). I’ve attached the style I’m looking for, and will send the three subjects I’d like drawn once we start speaking, but these will be:

1) Caerphilly Castle
2) Sultan the Horse (Caerphilly)
3) Interior shot of St. Martin’s Church (Caerphilly)

- PPH won’t let me upload more than three attachments.

All three pieces would be similar in size - around 10 inches (25cm) square, as they’ll be framed as a collection. The work would eventually need to be rolled up and carefully sent via post to my address in South Wales, UK.
