I have a university degree in economics and IT, and several decades of system design and programming, in the recent decade especially in Excel and VBA. In my approach you'll have opportunity to consult details with me, to test pilot solutions if necessary in order to achieve an optimal final solution. If you send me a sample file, I'm ready to create a free draft pilot for you.
Further use of macros, fixing of bugs and minor changes are included in the bid without any additional fees.
Regards
