Consultant recommendation for non-linear FEA?

in General
We have a couple of fairly simple mechanical assemblies (5-10 parts + some fasteners) and we know we always end up "over-designing" when using linear static FEA so we are looking for a professional with the right tools (and the right knowledge of the tools!) to do some analysis for us.
Anyone "know a guy (or gal!)" they can vouch for?

Is the non-linearity mostly material related or deformation driven?
are there plastic parts involved and do you have the non-linear material data (e.g. E secant?)
It's good old fashion metal (die cast aluminum and extrusions) so nothing too crazy or anisotropic…
We are designing to a peak test load that is a "once in a lifetime" (of the product) so we can tolerate some small amount of local yielding as long as we don't have a catastrophic failure or "excessive" deformation.
In our experience linear static analysis is always quite pessimistic compared to observed results when testing to failure.
Hi Eric,
I have worked with linear static FEA in the past.
I can help streamline the analysis so you are not over-engineering unnecessarily.
Happy to take a look.
