Kola I've just been through something like this, using Verisign.
You are able to carry out two types of transaction with them (as you should be able to do with most cc handlers). The first, authorisation, just sets the funds aside from the avilable credit on the card, but doesn't debit the amount from the card. The second, settlement (also known as capture), is done when you're ready to collect, at which point the card is debited. This would normally be when you deliver the goods, for instance. However, with Verisign (and I suspect others, too) you have to retain the original authorization code to send to Verisign when you want to collect. I don't know if 30 days is allowed as a period between authorization and settlement, but I don't see why not. Their documentation, though long-winded, is thorough. What you have to be careful of is cc handling companies that set the whole thing onto batched auto-capture, meaning that any authorizations done that day are sent for settlement at a specific time, without your requesting it - which sort of buggers up the strategy you are contemplating.
