My selling limit is £500 but I have an offer of £1k for a computer. What can I do?

As advised, and to add ... an item of that value needs to be shipped with adequate compenstion cover in case of loss, damage or claims of 'not received/non delivery' ... Royal Mail Special Delivery is recommended.

Thanks I was going to use Ebay UPS delivery.
