That line about her sending back something "so full of buzzwords that I didn't even recognize my own work" really stuck with me, because that's the exact failure I'd worry about. A resume writer who doesn't work in your field can't know which projects actually matter to hiring managers, so they just swap in fancy words to make it sound impressive. My question is, did she ever ask you for details about what you actually did, or did she just take your old resume and dress it up? Also, what field are you in, since that changes the answer a lot? Asking a friend who does the same job as you might get you better feedback than a stranger with a certificate.

Man, come on, pulling tack strip on every turnover job? Half these rentals, the strip is still solid and the staples are surface rust at worst. I've run carpet over strip that had a few old staples in it plenty of times and never had a callback, so the rippling thing sounds more like a stretch problem than a staple problem. Plus on a concrete slab you start scraping and chipping and now you're patching concrete, which is way more than twenty minutes and thirty bucks. Sometimes the smart play is just tap the staple heads flat with a hammer and move on. Your mileage may vary depending on how bad it actually is.
