URGENT: FIX RIGHT NOW - One Page Check Out on a LIVE Magento Store

Hello, We are a e-commerce and we are having problems on the one page checkout and payment module. The main problem is that we are in Brazil, the Magento is in Portuguese, and we are open right now, we need to be quick, also, we have 10 customers online every time. So we really need to do this quick. I JUST WANT TO HIRE, SOMEONE TO START WORKING RIGHT NOW, BECAUSE WE NEED TO SOLVE THIS, RIGHT NOW! 1) Update PagSeguro (Brazilian Paypal) module because we are having problems with this. You can do thru Magento Connect, but we need to set the right permissions on the server to copy those files to the server. [login to view URL] 2) Update Ricardo Transparent Module for PagSeguro. This is the module that we are having a little trouble, so what is happening is, I tried to install these two modules, but after installed, this module when a customer is on one page check out and select payment thru Credit Card payment, the infos where you write the credit card informations, doesn’t appear. So the customer can’t pay thru credit card. And many customers to choose the payment BOLETO, which i took off right now, is getting problem too. I can reach the creator since its paid, but he takes a while to answer. Before you touch the server, please make a full backup, when cann't stay off line. 3) ZIP CODE: Also, we are having some problem with the zip code, first, before, as soon you finish typing the zip code (CEP), the address would load and complete. But now its not loading, and also, there are many customers that say that it doesn’t calculate their zip code, for the shipping price.
