Crystal Report Consulting

For the time being, I'm using SAP Crystal Reports, version for Visual Studio 2010. So far, I can create Simple to Intermediate Report. I also can provide the data in table without any problem.

Unfortunately, I don't have expertise to play around with - Dynamic Columns. At certain rules, some Column will displayed. At certain rules, columns will not displayed

If possible, would you recommend Crystal Reports Consulting Company or Crystal Report Consulting People? A good one
