There are. Just Google Elsevier, find a few appropriate journals for your article and then email the editors of the respective journals to inquire about publication fee. Good luck!
Of course. I am a main editor of the Journal of Data and Information Science (JDIS) which is free for authors and open access (CAS pays the bill). The journal is refereed (like any quality journal; do not try to send rubbish), covered by Scopus, and covered by the WoS Emerging Sources.
The Journal of Universal Computer Science (J.UCS) is both, free and open access. It is afaik one of the oldest OA joirnals in CS. I'm a member of their editorial board. Impact factor is around 1.0 in recent years. Www.jucs.org.
