Hi R3plikate, welcome to Warseer. No time at all? That is a real shame! Warseer has trading forums where you may be able to sell some things, ebay or other auction sites still work, but can be quite hard work.
Last year i manager to sell a large amount of unwanted books and miniatures at a wargames expo (Vapnartak in York).
Where in the world are you? Might be able to point you in the direction of a good show to sell at.
