Hi, Im currently writing a business plan. The business will be in the mobile catering sector and It will operate out of a converted horse trailer. The trailer I’m buying is half converted, it is ready to go but in my opinion still needs a lot of work done to it especially the exterior. Here is my question - The exterior is spray painted black, I want to divide the exterior walls in to two halves, top and bottom, each being very bright colours. If i was to do this myself, bearing in mind i have no experience in sanding or spraying, how time consuming and expensive would it be in comparison to a professional job ( Neither do i know how much they would charge!) Any help would be awesome, I’m also on an extremely small budget so I’m cutting corners the best way i can Daniel.
