Pitch decks can be tough. Especially when you're focused more on the content but the design requires its own attention. In my personal business, I can come up with the content but the design was always of a road block. I have found Fiverr.com to be very useful, albeit you'll need to really dig into the service providers, but it can be very well worth it for the short-term and for a quick turnaround. The newest thing that I have been using is Canva.com. It's very simple and easy to use and its free, unless you use their premium images and even then its very cost-effective.

As a start-up myself, stretching every penny is key to surviving the first few years. I'd be happy to share other cost savings lessons that I have learned in my entrepreneur journey if you need help with anything else.
