There are quite a few Rice's in Union County, near Spartanburg, and also Anderson County, a bit farther to the west. You might start looking there--I'm looking into my own Rice family in that area, so if I find an Ervin Foster Rice I'll let you know... I have found familysearch.org very helpful--not so much the "search" template, but go to the bottom of the search page and click on United States and it takes you to a list of states with their databases that you can browse--time consuming and sometimes hard to navigate, but if you have some time, it's very interesting.
Here is the South Carolina section: https://familysearch.org/search/collection/list#page=1&countryI...
