If you have a specific need, working via a VIP day or over a few weeks/months would be the way to go.
Setting up Active Campaign or your tech stack, prepping the arrival of your first VA, setting up a launch or a 5day challenge, making sure you can go on holiday relaxed and really Off... all these things can be done via a short collaboration.
If you know you want a long term right-hand, retainers are a great way to go.
You get a trusted advisor and integrator that will turn your big vision into a big success without you losing your sanity.
I keep you focused on what matters and what helps your business thrive. (and yes, self-care reminders will be included.)
Anyway, from 15mn checkin on Voxer, to full on team & project management, there are many options to help you in a way that suits budgets and needs.
