Windows Multi User System

Looking for a professional developer to develop a Windows Multi User Database that stores Customer and Job installation and scheduling data in an SQL database. There will be 2 levels of security Admin and User, Admins will be able to add Builders, Products, run full reports, etc etc, and the basic user can enter details into the system and also run reports on upcoming installs, jobs not finished, etc I have provided a sample screen layout with tabs for sub data such as notes, pictures, documentation and service history. The default search screen is simply a list of jobs, with names, addresses, dates, contact details etc, from which a user can search on any field or sub field to pinpoint the relevant records. The user can then click on the job and bring up the job details as per the attached file. Note: System must be able to store pdf's, jpgs, etc for documentation and photos, and be able to have specific reports for the customer. Happy to assist in normalising the data structures with the successful candidate. Note: Happy to use any Windows development environment, doesn't have to be the list above - Visual Studio, etc. Please provide justification for your choice. Only apply if you can show previous experience as I do not want to waste my time with developers trying to build their knowledge as they go.
