Hey agents, I have a client just looking at a business plan at buying Sprinter van for 15ppl for transport to local towns in TX. They own a wedding venue and want to offer as additional service to wedding party. Probably about 30 trips a year. Any ideas what this would cost? Just looking for budget at this time. Keeping it separate from wedding venue. Thanks for your help in advance!
