Inelastic FEA of steel beam using ABAQUS

I need someone to provide me with an inelastic analysis for a special type of steel girder I am working on. I have already developed the elastic model (eigenvalue analysis) so I will provide the file (created on version 16.4-2) which includes the geometry/mesh/load and boundary conditions. In the inelastic model, I need to include the initial geometric imperfections and the residual stress pattern. The geometrical imperfection will be taking as the eigenvalue buckling shape reduce to maximum deflection of (Lb/1000). I will provide the residual stress patterns for this specific girder (2 different patterns to be used separately). The analysis will include a first step to establish a state of equilibrium and then a second step to perform the buckling analysis using Riks method which is already available in the software. Additionally, I would need a technique (could be a short code or short tutorial) to apply this technique quickly since later on I will need to model more than 250 beams and I don't have plenty of time to do all the work at the moment as I am occupied wit multiple other projects. More details will be discussed later on and if you have any question please don't hesitate to mention it in your cover letter. The Price will be adjusted depending on the work quality, what you are going to provide me, and how much it will make my work easier for the parametric study later on.
