If you are sure you can pack it safely, it will not be treated very well on its travels to Italy, the shipping is not too bad. Where it may go wrong is the VAT and courier charges so I need to do a bit more checking.
I'm in absolutely no hurry so you would have plenty of time to pack, but it will have to be a sturdy box at that weight.
I would arrange the pickup, I'm afraid they only usually specify a day and not a time, send you a label to print and I will pay all the charges before it leaves you.
If you're still happy let me know. I can't stress enough though that it will have to be well packed.
