You are at the right place! Put prices beside each of them and you will be getting offers.
Pictures always help to see what accessories are included and what is the fig condition (paint wear, broken parts, etc.). So you may open a free web based picture album like Picasa or Photobucket and post a link at the end of your list.
About getting private message (PM), you won't be able to reply to PM before posting at least 5 times.
If you don't know the value of your sets, than make few search on eBay to give you an idea. Keep in mind that on this forum, you are saving eBay fees (insertion, final value, additional picture, etc.)
Good luck!
