I thoroughly recommend Solvu for Excel design

Linda proved a real find to develop an auction program for us.  She is in WA, we are in Victoria.  With phone, email and remote desktop viewing this was not an issue.  With careful and focused questioning Linda produced a set of form mockups and after some alteration they defined the inputs and outputs.

Linda produced the program and ran though it on her desktop with a remote viewer.  It produced the expected results but we discovered some changes that would enhance it.  Linda included them with no problems.   We now have a great program with support available into the future should we require further enhancements.  Working with Linda was easy and she produced a simple to use and elegant solution for us.  I thoroughly recommend Solvu for Excel design.
