Netsuite & Shopify set up help

Looking for a support/direction expert to help us on setting up our linked cloud system <Netsuite-Celigo-Shopify-Zendesk>, I have to imagine that tons of companies function on an identical platform. However, setting up with each of the company reps is tough because no one will overlap the other with support. For example: Netsuite specialists cannot give us best practice standards to configure Shopfiy to flow correctly….and Celigo specialist will not install the smartconnecter tool without Netsuite & Shopify configured “correctly”. If you have experience and can walk me through the best way to configure our sites this may be a start at helping us with other projects.
