A) No problem. You can still take full advantage of
ZenATS. All you need to do is add few links from your existing website to ZenATS
For example, you can use your ZenATS to create a career
center or employment opportunities site for jobseekers to submit their resumes online or showcase your current openings etc. All you need to do is add a link to your current website to respective pages
created on ZenATS and it will save you hundreds of dollars, which otherwise you might end up spending for programming your present website.
