Turn designs into artwork for greetings cards

Hello

I'm a textile designer and I've been asked to turn some of my fabric designs into greetings cards. I know nothing about printing and print quality so I need someone to take my original artworks (these are not on a computer, they are collages with paper and fabric) and scan them in , add text and get them ready to be printed by a print company.

I need quite a bit of guidance as I have no photoshop/illustrator type skills

Many thanks
