Advice on flying bikes out of Vilnius airport

Hi Guys, We are an Australia couple touring down from Norway. Because of an inability to get a Ukraine visa we need to fly our bikes from Vilnius to Moldova. Do you know: 1. If they sell bike boxes at Vilnius airport. 2. If there is a taxi company or alternative that could transport two bikes plus all our luggage to the airport or 3. If there is a bike shop that could assist. Any advice would be appreciated.
