Can I get help with my Cash Awarding System?

I'm looking to get this script changed so instead of it awarding all the players at the same time, it's a local script in the Gui so each player gets cash at different times from anyone else, but I can't seem to figure out how. Can anyone help?

local moneytime = 300

while wait(1) do
    moneytime = moneytime - 1
    if (moneytime == 0) then
        moneytime = 300
        playersa = game.Players:GetChildren()
        for i = 1, #playersa do
            playersa[i].PlayerGui.Cash_V2.Shadow.Cash.Text = "Awarding cash..."
            wait(1)
            playersa[i].cash.Value = playersa[i].cash.Value + 50
        end
    end
    playersa = game.Players:GetChildren()
    for i = 1, #playersa do
        playersa[i].PlayerGui.Cash_V2.Shadow.Cash.Text = "You'll receive $50 after " .. tostring(moneytime)
        playersa[i].PlayerGui.Cash_V2.Shadow.UserCash.Text = "$" .. tostring(playersa[i].cash.Value)
    end
end
