Support for Slovakian Roma children in schools

Dear Czech Sheffield Society We have many new Slovakian Roma children in our school. Does anyone have any contacts about how I can locate Slovak speakers who are qualified to support these children.I have had no success with the Local Authority etc. Students or the non- teaching partners of visiting academics are likely to be suitable candidates to offer these children in-class support. Our school would provide arrangements for CRB checks & offer payment at a sessional rate to be negotiated on the basis of a successful,informal interview. If anyone can help please reply here in the first instance. Many thanks Gilly Robson
