Driving lessons/Instructors

Im currently looking for an ADI to do my driving lessons with but cant seem to find anyone with much availabilty for manual, im having anxiety about starting so would need an instructor that is good with dealing with nerves, £30-£35/ph is my limit and also thinking about buying a 10-20 hour package rather than singular 2 hours, i was looking at driveJohnson because their prices are quite good but theres no info on the actual instructors and their availability. Could anyone recommend instructors? also LE4.
