talkaction:

local config = {
    itemid = 5957,
    storage1 = 224413
}
function onSay(cid, words, param, param2, channel)
    if param == '' then
        doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_BLUE, "Command requires param.")
        return true
    end
    local t = string.explode(param, ",")
    local creature = getCreatureByName(t[1])
    if not creature and isPlayer(creature) and not isPlayerGhost(creature) then
        doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_BLUE, "Invalid param specified.")
        return true
    end
    if os.time() > getPlayerStorageValue(cid, config.storage1) then
        local days = tonumber(t[2])
        if days < 2 then
        doPlayerSendCancel(cid, "O mínimo que você pode transferir é de 2 dias.")
            return true
    end
        if days and type(days) == 'number' and getPlayerPremiumDays(cid) - 2 >= days then
            doStartTrade(cid, creature, doPlayerAddItem(cid, config.itemid, 1))
            doPlayerSendTextMessage(creature, MESSAGE_INFO_DESCR, "O Jogador " .. getPlayerName(cid) .. " deu trade em você, e está disposto a trocar " .. days .. " dia(s) de VIP.")
            setPlayerStorageValue(cid, config.storage1, days)
        else
            doPlayerSendCancel(cid, "Você não pode transferir essa quantidade de VIP.")
        end

    end
    return true
