I am a PhD student and research assistant at a German university. I recently did a CFA for scale validation using my own research (survey) data and am familiar with the requirements and current literature regarding CFA/SEM. I can help you with the CFA measurement model, deliver all scripts and codings and a report that meets academic standards. I would be employing the R lavaan package. Looking forward to help you assessing the possibilities depending on your requirements and data. My first stept would to assess the feasibility of your desired models (number of latent variables, number of measured items per variable, total sample size, scale level of measured variables, missing values, multicollinearity, sample size in groups, etc.). If I deem the project feasible, I would continue working with you. Just drop me a line here if you are interested. Best, Benjamin
