English and Spanish tutoring for middle and highschool once or twice a week.

I hope you are doing well. We have two children in 5th and 8th grade, ages 10 and 12 years old for whom we want tutoring. Our 12 year old is in honors language this year but our goal is to get her ready for English and Spanish. As for our 5th grader, she is in advance math in her class and we want the same for her. We live in New York, how can we make this work?
Please let us know what you offer, how your tutoring program works and how we can get started with tutoring.

Thank you and have a great day.
