Shopify Assistant required

My Shopify website www.moonshinesales.com . I have had it turned off for a couple of months. I believe I have had my website built to a fairly present full level and may want a bit of tweeking. I have not successfully advertised it with minimum sales as I am limited in knowledge of internet workings at that level so I’m looking for someone that can do it for me, happy to Have it work on and maintain it, if successful I am prepared to split the profits 50%-50%. I will pay all fees up keep . So if you are interested you may lay out a course of action you would undertake to get the ball rolling. Look forward to your proposals .Thanks Rick.
