Professionalise our Business Sales Deck

Hello, I've put together a sales deck for our business, HelloDone (www.hellodone.ai). It's fine, but I'd like it to look far more professional using the colour palette from our website (don't have the original RGB numbers) and your imagination for making it look more engaging. I've uploaded the deck as a pdf to start with, once we're working together i'll forward the ppt. Ultimately I'm looking for someone I can come back to for repeat business with decks / 1 pagers / linkedin graphical posts.

Best,

Ed
