The Cost of Rust Consultancy

Does anyone know what would it cost me to get tailored training from a Rust consultancy (like Ferrous Systems or Integer32) for a team of 5 members? The project involves implementation of a network protocol stack on embedded systems and WebAssembly.

(I'm applying for seed funding in my country and the deadlines are coinciding with Christmas holidays in the West. So, I've filled out the "Contact Us" forms for these consultancies but I don't think I'll get a response until way later after the holidays season)
