Food Costing Website Needed.

Are u are Developer ? We are located in the south Island of New Zealand and are currently in the hospitality business. Over the current years myself and my business partner have work with alot of food costing and roster programs web based and program based. We are now at a stage were we would like to take what we know and develop a streamlined and functional web based Food costing and menu writing website for chefs working in NZ and is very easy to use and will take the load off any chef as the website would do all the costing for them. The specs for the website are as follows **We would like the website to let the user write recipes, menus and methods while storing all there items online for them to access at any given time. ** We would like the user to be able to cost any recipe or recipes for costing purposes as well as give a full costing report and printable version for there current project. We have some of the calculations in Excel form as well as a costing program in MS Access that can be used as a guide. Thanks you .
