magento 2 squareup extension syncing orders

I'm looking for a Magento expert that can do this job for us, sync (import) orders from squareup POS to Magento 2 customising the squareup official extension as it's not doing it right now, I got in touch with support and they advised we should and I'm quoting what they said after checking our website, "To have this orders imported would be necessary to customize the Square extension code as below: On Model/SquareOrder/[login to view URL] Modify this line: if (isset($fulfillments) === false || isset($tenders) === false) { To this: if (isset($tenders) === false) { On Model/SquareOrder/[login to view URL] Modify the makeStreet method, to check if $order->getFulfillments() has any fulfillment and address on it. If it does not, then a fake address needs to be set instead of the one from the Square order." when I enquired they state it shouldn't be a big job if you know what you are doing, kindly if you are not familiar with this or worked before on Magento don't bid, ideally, this shouldn't take more than a couple of hours. Thanks for reading,
