who can do frequency/deflection/stress analysis for me?

I cant justify the cost of simulation package in solidworks.

We are only having a new design requiring these calculations rarely anyway.

However our hand (spreadsheet) calculations aren't very accurate, and the assumptions for one assembly corrected against reality dont carry over to the next all that well.

So are there people out there with access to simulation professional who can do this work cheaply and efficiently?

Simulation express is SO annoyingly crippled.
