Web based system for small scale industry automation.

I am looking to hire either a team or an exceptional individual to work on a small web based automation system. We need to develop a web based system where data input of dimensions etc are fed into the system after which it goes through and checks if the dimensions are all within acceptable parameters and accordingly processes an invoice and/or goes into inventory. Ideally this would be done using mysql and Php running on a local server. Three terminals will be involved in this process. Each will be logged in with 3 different users. I will explain the complete details and the process through a skype meeting once i shortlist prospective teams/freelancers. I require complete professionals for this as I have have the system ready on the date specified. If you have experience implementing systems like these or simmilar then it will be a plus. I will only select reliable people. Thank you.
