A proposal does not have to be long to be persuasive. It has to show that you understood the client's need and that the next step is easy. Here is a structure that works for most small service businesses.
Open with two or three sentences that restate what the client asked for and why. This shows you listened, and it lets them correct you early.
List what you will deliver and what you will not. Scope that is specific protects both sides: the client knows what they are buying, and you are not asked to do unpaid extras.
Break the work into stages with dates or durations. Say what you need from the client at each stage, because delays usually come from missing inputs.
Tell the client exactly what to do to proceed, for example 'Reply to confirm and pay the advance to start'. A proposal without a next step often stalls.
Keep the structure fixed and change the need statement and scope for each client. That balance gives you speed without sounding generic.
