Shopify Expert to finalise logisitics integration in Shopify platform

We have a completed website and are close to completion of our online shop but require assistance from a Shopify professional to finalise the finer details of the shops functionality. A brief background is as follows: We operate a manufacturing facility that prepares products for sale to both third parties and our retail stores (customers can order to either location). We have integrated Zapiet to handle our local and store deliveries where we have company local delivery functionality within set delivery zones (set fee) and to our retail outlets (not sure if the shopify local delivery app is the best option in addition to using zappiet) We have integrated shippit as a third party logistic provider for deliveries outside of our standard zones. Complications: Using Zappiet, Shippet and Shopify local delivery all together – is this the best solution Require delivery output for our drivers to manage orders as they are picked and delivered so our customers receive timely notifications. This work will include but not limited to: - Determine and integrate the right delivery apps to achieve our end goals as outlined above - Advising the best process for orders, deliveries and finding an app that our drivers manage to notify customers of delivery status - Coding new templates: - Customising packing slips - Creating and customising notifications that are sent to the customer and our factory teams - Creating and Customising tracking notifications upon pick up and delivery Please be aware we do not need any other web development services, our website is complete.
