Thanks everyone for your replies. Myself and the employer initially were each quoted quite a large sum by a visa agent who was quoting us for doing everything from start to finish (Compiling, making the documents, etc). We had the idea that we would be able to do it on our own, tbh I think we'll probably be able to get most of it on our own, However, I'll discuss it with my employer about maybe getting a visa agent to do a final check on the documentation for both the employer nomination and my own application, as opposed to the visa agent doing " the whole thing ". Cheers
