Are you trying to make  contact with a professional programming service so
that you can pay to have a spreadsheet developed? If so, then post a reply,
including contact details, and people on this forum who provide professional
programming services will possibly get back to you with information on what
they charge.

Or are you asking someone to do a development for you for free? This is not
a free programming service!!

Please read http://www.catb.org/~esr/faqs/smart-questions.html to learn how
to ask proper questions and then feel free to ask questions about specific
problems you are having.
