Dear Sir/Madam:

Credit Suisse First Boston Equity Research Department has turned to Rhapsodyos for assistance in the programming of a complex minimization problem that arose in the deregulatory environment that we attempted to model. This was a complicated project that needed to be completed under strict deadlines. Another complication arose as some members of our team got involved in the project at the same time with Rhapsodyos and were catching up in the process. .

Rhapsodyos provided to be a capable, reliable organization that not only answered our questions but often came back with unique innovative solutions to the problem posed to them. Rhapsodyos provided programming support, mathematical algorithm and even proposed an alternative solution to the problem.

According to our wishes, Rhapsodyos created an interface that read data from Excel, conducted calculations and provided output in the Excel format. The interface is easy to use which was very important to us. We are very satisfied with Rhapsodyos's performance and would recommend the firm to anyone who wishes to receive reliable results expediently.
