It will be fruitful if you do a google search, read up and start preparing than to simply sought the easiest way, start a thread ask and expect a list of info provided to u free. BTW there is another thread with tons of info regarding Vietnam in this forum. If u are lazy to read, ask there n u might have better chance of ppl replying to you.
Ya, I think TS should not expect to be spoonfed.
TS, do your own research. With google and sites like wikitravel and wikivoyage, research only takes a couple of hours to get a basic itinerary, which you can refine and post for comments.
If the info is too overwhelming, the least you can do is tell us what you like to do/see/eat/buy. Only you know what you like. With a topic of focus, then we can help you.
