Would any of you recommend RAC to cover cars for a business?

So Im wanting to start a luxury travel and private hire business. But I'm very new so was looking for any suggestions from anyone regarding the insurance and how it would work etc.. I already have a website www.whittingtoncars.com - hopefully this gives off the image of what I want the business to become. The site is constantly changing etc.. So yeah any feedback regarding insurance policies or if theres anything else out there thats more worthy

Many thanks, Robin
