Crowdfunding and also donations from friends

My partner keri has suffered through mental health problems and depression since her son was born stillborn , every year on her birthday she donates her birthday money to the unit that helped her , she has recently got out of abusive relationship and sorted her mental health problems , she has always dreamed of one day giving him a headstone but due to her previous situation she financially didn't have the money so she had to opt for him to have a small free plaque with just his name , she couldn't even have a chance to give him a personalised message , my aim is just to raise enough that she can finally give her son a headstone with a message from mummy , my aim is a normal height headstone shaped as a bear with a heart inscripted with Peters name.
