If someone wants to prune your tree, check them out with the Better Business Bureau first. Ask them for references and look carefully at their past work. Lastly, check with your local county extension agent to be sure their methods and their timing are correct. Your tree is worth much more than this small amount of your time. It's too early to start vegetable plants indoors, but it's time to get those lights ready.
Seedlings do poorly on window stools because there's too little light in early spring.
An overcast winter's day provides only about 600 foot candles of light, and that's outdoors. Inside, that's reduced to only 50 to 300 foot candles. Plants need several thousand foot candles of light to keep from getting spindly and weak. Since light intensity decreases as the square of the distance from the source, keep the lights just slightly above the plant tops.
