Is there a way to amend the shipping cost after the purchase by any chance, I think tis would be the best outcome. We have already put a message that we will contact the customer regarding the shipping cost as it's free after e certain amount.
native PS does not allow us to amend an order with additional shipping, unless you make that cost a product.
This module looks interesting, but there may be others similar. Usually you can find a solution on addons that does most of what you want but the beauty of open souce is that it's easier to customize a module that gets base feature.
"This module is great tool for merchants which needs to somehow customize the shipping details after the customer already placed the order. The merchant can change carrier, shipping cost, weight and tax rate."
