Adam,
We do not sell any insurance here but try to point people in the right direction with their questions. Since you are 21, you should not have any problems in getting car insurance for a couple of days. Some insurers charge a fixed rate per day but you do get a discount if you want cover for more days. Other insurers will take your driving experience, no claims discount and other standard factors into consideration before giving you a quote.
You can expect to pay anything between £11-25 per day of cover. If you want a list of websites where you can get an online quote, just let me know.
