I can do what you want because I have worked with Excel for 20 years.
I can work under a Confidentiality and Non-Disclosure Agreement if you want.
I can start tomorrow, if you pay the Retainer Milestone into the account and send me your existing material. We can then agree exactly what it is you want me to do for you.
When I wsa a senior manager at a big multinational I designed spreadsheets, reports and dashboard that were used in more than 100 countries, I now work from home in the UK across five freelance sites, and many international clients have used my skill in VBA programming, formulae and conditional formatting.
Because you have made this a 'restricted' project, I cannot send a Private Message or attachment.
If you do contact me I can then send you an example that will let you judge for yourself whether I can do what you want
Look forward to hearing from you
Bob Allen-Turl
