Rules regarding pickup only and COD

Not sold on ebay for a long time due to my dislike of paypal but wish to list a few items that would cost too much to post.  I take it I can state pick up only and if someone buys and wants it posted I can cancel the sale with no negative feedback?

Also I do not have a paypal account but it seems ebay will not allow me to state COD only? If someone pays via paypal and I have no account then what?

Last thing is considering the items value is it right I ask anyone who pays via paypal to sign a document on pickup that confirms they have picked up the item and have inspected it to cover myself from false paypal claims? Might sound paranoid but it does happen.

 

Thanks.
