Hi everybody,
I need to write a proposal concerning an industrial attachment that I am doing in a particular company , so wanting to quit it and enter as a staff. So I am be asked to write a proposal, so please how do I write the proposal.

I'm not 100% sure I know what you are asking, but generally the best way to approach a proposal is to make a list of the main points that you absolutely must cover, then write a couple of paragraphs or whatever is necessary to explain them fully.

Start your proposal with what you want, go into details of exactly what is involved, give details of all the advantages to them of what you are proposing, and then do a quick summary at the end.
