Structural Engineer Needed for RSJ Size Calculation and Plans

I am looking for a qualified structural engineer or architect to provide detailed plans and calculations for the installation of an RSJ (Rolled Steel Joist) in a load-bearing wall. The site is a two-story building with roof load-bearing walls located in Birmingham, UK. The plans must comply with UK building regulations and include specifications for the RSJ size to support the structure safely.

Please provide your qualifications, experience, and estimated timeline for completion.
