Fashion Photography Pro (Frustrated!)

I want to create my own homepage and NOT use the theme homepage. For some reason I cannot get rid of the theme homepage even if I create a separate page the theme one still shows up and my home page is nowhere to be found.
The reason I want to remove the theme homepage is because there is a lot of stuff on there that I don’t need. If I click on (don’t show this specific item) it creates a large blank space that I cannot fix or it doesn’t remove at all.
Also the top right hamburger menu with the extra contact menu I cannot seem to find ANY information in the backend of that to change it (my logo) it still shows up with the theme logo and I have no idea how to edit this.
Also how can the footer copyright be changed? Is there a way to remove the ( Developed by Themagnifico) at the bottom? Seems silly that we can’t after purchasing the theme.
I am really frustrated at trying to edit this and I feel like it shouldn’t be this hard. Please let me know if you can help, any suggestions would be useful at this point. The link is http://www.davidcraigart.com
Thank you.
