Summer company classes

Looking for a native, TEFL qualified, English teacher to do 1:1 classes, online this Summer. Each student will receive 2 classes per week of 1 hour  (there are 7 students) all with elementary level, they are company class students. As the students have low level English, teachers with a higher level of Spanish will be given preference.
Students are being sent abroad on a project and need to improve their level. We have excellent materials for the teacher to follow.
Some details need to be fully confirmed but are looking at the classes to be given in the mornings to start asap and will go July and August.
We expect that applicants will have some holidays booked, so will look to fit in with that, July ideally however should be a full month of classes 
Though we would consider freelancers in the summer, we are Ideally looking for teachers who want to work on contract, as post Summer we will be considering the same teacher for further classes.
