I am finishing up my website for my local fitness company. But I want to do some optimizing for speed and just some general back office recommendations that should be done. I have tried w3 cache but I only made the site slower. Is it safe to outsource this to Fiverr with all my papal data set up? Or should I remove the logins and api's from the carts before I give someone privileges to the site? Or am I just paranoid that someone would scrape this financial data.
