Botanical drawings

We are looking for a person that can make botanical drawings of several (approx. 35) different plants.
E.g.
Agastache mexikana
Antirrhinum majus
Borago officinalis
Bupleurum rotundifolum
Calendula officinalis
Callistephus chinensis
The style we look for, see the attached picture.
Each plant with flower must be drawn seperately, but we also want 6 different final versions where the plants/flowers are mixed.
