# Discovery call with Philippe Maza · Fortis Motion

> This call takes 20 minutes. You tell me where the store is and what is in the way, and I tell you what I would do about it. If you already run ads, we look at the account together. If you do not, that is fine too. You get the price on the call. Nothing gets signed there, and the proposal comes by email after.
