The pay varies by the position and client you choose to work for. It can range between $9 - $18/hr but averages around the $12/hr. You have full autonomy on who you work with, so you have the control over how you much make.
You can take a look at https://enchantedglobal.com/jobs/arise-opportunities to see what the pay rates are, if you are not registered with Arise you will not be able to see the company names.
Pro tip: Choose a fun project starting out, then choose something more stress down the road, you are able to work multiple contracts at the same time so always have something stress free you can fall back on.
