I’ve seen people confuse cheap and quality. Some sites market themselves as the best writing service, but the real measure is whether you can communicate with the writer and get revisions. Services that offer free revisions tend to produce higher quality results — worth asking about before ordering.
Structure it like this: Hook → Why this subject lights you up → What you’ve done outside class → What you’ll bring/contribute → Future goals (tie back to the uni). Keeps it from becoming a random life story.
