Hi there!
I have experience working with Canva and know enough about the system to know that Canva does not support the conventional iframe method of embedding presentations onto websites. However, I can help you go around that, and in return, all I ask from you is compensation and a great review from you.
With any of my projects, I will give you the entire source code, and any documentation explaining how everything works together. If necessary I can even help you get the site up and running so your presentation can go smoothly.
If you're interested in working with me, please feel free to reach out to me and I will be happy to help in any way I can.
Cheers,
Siam Shafiq
