As for your FAQ part - why on earth would YOU even bring up a question asking “Why do you have bad reviews”. ugh!! Nothing like kicking yourself in the teeth! Never, ever, ever be negative about yourself - even IF there are negative things about your work, life, personality etc - people love confidence (not cocky stuff, but you know, those who have self-esteem). There is NO reason to even mention this last thing on your FAQ’s as well as some of the other ones too, but, I am not in your category, so maybe you need to explain “why so cheap” - those make me cringe too.
I would get rid of that last FAQ - you have the opportunity to respond to negative reviews already. Use that to show your professional side to those you could not make happy, regardless of whether it was your fault or theirs.
I think having that last FAQ just puts like a neon blinking sign that is subconsciously telling the buyer to “go look at those bad reviews this one has!!!”
You never want to emphasize or draw attention to the negative or your flaws - always highlight your strengths. Always!!!
