Calcs and Drawings for Extension and Conservatory Modification

Hi, I am looking for a structural engineer who can also do some basic CAD drawings. Basically I want a bay window extension to the rear of my house and I want to convert my existing my conservatory to a solid roof.

I need calcs for the steel for the bay window opening, and calcs for steels for the conservatory modification. Along with a drawing of the rear with the bay window extension and with the conservatory solid roof.

I can provide existing scaled drawings of the conservatory and the house.
