Hi,
As a database specialist, master and trainer for the past 12+ years I am sure I am the best candid to get this project done exactly as required and with the efficiency and specifications you want.
I have been building databases and maintaining them on almost all platforms and for most industries including logistics, medical, hospitality, retail, education, mining ,marketing and even non profit organizations.
I believe that you are probably currently using some form of spread sheets to keep track of everyone and everything and I understand what the issues and concerns are when using that model.
If you could send me your project brief, and some samples of the information that you either have, or intend to gather, I would gladly consult and do a mockup of how your system can be developed at no charge to you. Once I have reviewed everything with you, we can proceed to getting the system built and ready for you to use.
Most developers will build the system, deploy it and then leave it up to the client to get all the information and processes in place using their own staff. I offer the additional benefit that once the system is done, I'll load any existing information into the system for you at no charge.
This allows me to capture any small errors that might appear, and since I can populate a system with 500 000 entries in less than 15 mins, after the data has been cleaned up, I'll save you time and effort getting staff to load existing data into the system.
