There's one place in the first paragraph that suggests that you aren't a native English speaker, but that's a minor point. My impression is that tidiness and reliability, and possibly being service-minded, aren't things you say about yourself, unless you can say something like "reorganized the widget inventory, increasing the efficiency of shipping orders," because very few people think of themselves as unreliable or messy. And anyone who really doesn't think of themself as service-minded would either just not answer this job ad, or if they really want the work for other reasons, decide that they can probably manage tidy enough for a few months.

That said, I haven't successfully applied for a job (rather than a freelance gig) in over a decade, and am on another continent, so if someone with more recent or local experience disagrees with me, you should probably listen to them.
