might be selling ball python

ok i have a small ball python still just a little guy a bout a foot (haven't measured him yet) but i am willing to sell him he is very nice, eating regularly on live partly-grown up mice. and i will be willing to sell him but i have no experience on selling snakes and shipping them etc.
so if you want to post a price im lookin for about 40-50 dollars (tell me if thats too much) ill try to post some pics of him. just so you dont worry he is all healthy, but he still has eye caps from his previous shed that is it.thx alot srry that im like a complete noob when it comes to selling snakes

i may be interested in buying him
but before anything... a few questions:
where did you get him and why are you selling?
how long have the eyecaps been stuck on?
only a foot long and already had a shed and eating fuzzy mice?
how do you know hes healthy?
how do you know hes a he?
