Jts Standard air rifle

How do you sell above mentioned air rifle. I bought it new but its to heavy for me, has less than 100 shots. It is just absolutely too heavy for this old man. I have damaged both shoulders and can't shoot it except on a rest or gun vise. Like brand new and shoots exceptional also has the 1/2 x20 adaptor I ordered. I am totally new to pcps and air gun forums. I need a Umarex notos if I can sell this. Can someone please give this 74 yr old disabled old mansome pointers as where to start. Also not very computer litterate.
Thanks for reading Larry
