Here at fancyAcar, we do not not sell any insurance products I'm afraid. However here's a list of companies which do short term car insurance which you may find helpful. I suggest you give them a call and see what they can offer you (there's only 7 or 8 in the list).
I've just realised that you needed the 20 days car insurance starting from yesterday actually. I hope you have found what you're looking for. If you have, I'll be interested to know which company you got insured with and for how much. If you haven't and need help, just ask.
