Logo, icons for categories, illustrations for categories, picture collage

Hei,
So I have the following project:
I need the following:
Logo for my solarsite (Solcellepaneler.com)
Icons for categories (Solarpanels to commerical buildings, solarpanels to houses, solarpanels to farmers, solarpanels to cabins, solarpanels to appartmertbuildings)
Grahpic images to the same categories as described above (these will featured image on each page for each category)

Everything should have the same "theme" in terms of color.
