In my line of work, I have had to prepare hundreds of quotations for jobs, contract, requisition and request. When I started, I had to look at the templates there, but as I continued I decided to do a bit of research and personal modifications.
You need to note that your quote for the job will either give you the job or otherwise.
First, make sure you itemize this needed for the job and properly describe them to the understanding of whoever will approve it.
Second, the quantity of each item must be stated, this is important because it shows you understood the job or work.
Third unit price should be added to items requiring it then the total price.
Finally and most importantly, let you total price for the job be written in figures and words and in bold characters, this is most important because that is the area of interest for anyone approving it.
Much to say, but with those above your quote will be very presentable.
