Kitchen showroom/fitting

Hi all. I have been fitting kitchens and bathrooms for many years now along with all building work. I have toyed with the idea of opening a small kitchen/bathroom showroom and would appreciate any advice or past experiences anyone may have. Basically i prefer to work on all jobs personally so i would only target approximately 4 jobs per month which i feel would more than cover overheads and would keep me constantly busy and booked up in advance. One job should cover overheads and the rest is a bonus. I feel that having a showroom would give potential customers the opportunity to see what i can do and also give them the security of knowing where i am based etc.
As i am skilled in all aspects i can offer a complete service including all building alterations, tiling, flooring etc.
Many thanks in advance
