My Military Memoir

I'm sad that I have no idea what my grandfather did in WWII. I don't want that to happen to my family. I'm hoping to publish a permanent account of my time spent in the military for my children and grandchildren to enjoy. I've tried to find a publishing agent but thats like hitting the lottery. My next option was going through self publishers. The cost to self publish this book is more than I expected. I'm looking for any donations to help me accomplish this dream. Thank you.
