First, good luck with the challenges you face. Patience and dedication can help you overcome almost anything you face.
Now for a bit of advice... do you have anyone in your family that enjoys computer stuff? My wife loves to do the computer side of the photos we take. She is a talented artist, so I am lucky to have her helping with the PP work. If you happen to have someone in your family that likes it, maybe you can have them help? And if it is a younger person, maybe you can give them a little if stuff starts selling... Always nice to have the reward option!
Once again, good luck with this! I hope things work out well for you and that sales and such start growing for you.
