New to the Window cleaning business

Hello all, I own a landscaping company and I want to start offering WC to my clients. However I have a few questions. Do you guys offer different packages to your customers or are all jobs one size fit all ? For example are there some jobs that are strictly exterior washing only, are there some jobs that are interior only, or is both interior/exterior standard practice on all jobs? Also how do you guys price by window or per hour from your experiences which ways work better ? Also any other tips would be great thanks



Thanks

Brian
