hello there,
I have very good experience creating databases, but if you want to create a shared database you will also need an application that can run SQL queries.
This quote is ONLY for the database creation, we should talk later about the application.
Answers to your questions:
• Would you be able to install a SQL database in something like MySQL on a Windows computer? Or would it require an actual SQL Server? Both MySql or MsSql server can be installed on a windows computer, we can have a database "server" on that computer too. It does not need to be on the internet at all (only if you need access from anywhere and not just an office).
• Approximately how long would it take for the database to be built? Depending on the requirements, how many data do you have on the file?
• How much would it cost to build it? Again, the cost I'm giving you is only for the database.
• Will you support the database if we needed support? Of course, more even so if you need me to create the application to properly access the database.
Greetings
