spice modelling

I am looking for an experienced freelancer to create an intermediate-level spice model of an op-amp. I have specific parameters that need to be modeled, so the model should represent these accurately. The model should have adequate detail and accuracy for use in verification and design simulation, and should be able to accurately fit an equivalent circuit. The right individual for this project should be highly knowledgeable in circuit simulation and modeling, and possess the necessary theoretical knowledge to efficiently complete this task. This project requires the utmost attention to detail and great analytical skills, so anyone interested in this project needs to demonstrate that they possess them.
