Letterhead & Powerpoint Template Design for a Commercial Solar Company

C'est ce qu'une entreprise en/au(x) United States recherchait pour leur stationery design

We need these designs for a growing commercial solar company in Austin Texas. We specialize in large-scale/commercial installations. Any assets we design should have the following elements/considerations.
-Authoritative
-Crisp
-Professional
-No Cartoonish Graphics / nothing "cute"
-Should feel more like an engineering firm style than what you typically solar companies
-Not overwhelming

Ultimately are looking for the following in this design
-Letterhead design
-Powerpoint Design (horizontal Pitch deck with a title page design template 3-4 different layouts that we can alternate or use as needed)
-Proposal Design (Vertical layout that has a very professional title page and then just a standard template for interior pages)
-Business Card

Preferred fonts are Inter & Roboto
