Cost for eavestrough clearing

What would be the price to clear all our eaves troughs of debris, leaves and pine needles and thinning about 2 metres of a Japanese maple along the centre section of the garage trough? The troughs are one piece aluminum.

The house is a 2,300 sq. ft. two story, Salt Box style. The rear is a walkout basement with a grass base for ladders. There is also a 24 foot long deck off the main floor that will serve as the base for ladders along that section.
