Front end slider needs to pop in window for a large image and finger swipe to scroll images with small thumbnails for responsive. When vehicles are entered it needs to Auto populate a search option on the front end so people can find the vehicle easily. Backend it needs to be easy to add vehicles, make, model, year, all other specification options. All items can easily be editable.

"SOLD" When this is clicked it automatically takes it out of the inventory visible on the front end but we'll save it in the back end for future reference. Reports. Each vehicle will have expenses such as. Tires, windshield wipers, vehicle inspection. Each vehicle I need to be able to enter purchase price and then I can add expenses for that vehicle. It also needs to have sale price so that when the vehicle is sold I should be able to have a report that shows what the profit is and the expenses. It also needs an area for regular business expenses like: gas, supplies and etc. I would like to be able to choose what type of options to be able to print reports. Daily, weekly, monthly, end of the year or whenever. Please see a sample screen shot of layout for front end and see backend here [login to view URL]
