Virtual Assistant questions

1) If I were launching a soloprenuer business as a virtual assistant, how might I offer results ahead of time? Do I offer 20 minutes worth of work for free? The just-created website currently says, “Schedule a free consultation today” but I’m not certain if a free consultation qualifies as results ahead of time. It doesn’t say what they’re going to get exactly in this call, but I’m not sure what their particular tasks/issues might be. I also don’t know what I would put on a blog or podcast as a V.A. to make that a source of results ahead.
