WordPress Plugin Customizer/Developer (esp. Amelia & WooCommerce Bookings/Appointments)

We're a small startup that has most of the features for our site working, but we need 3 key components finished (due to the previous developer not doing the work) & they need to integrate with our existing WooCommerce payment system. We're not looking to create new plugins, but rather to use either Amelia or WooCommerce Bookings & Appointments to integrate 1)Scheduling of Appointments between Customer & Employee; 2) To match that with the Calendar availability the Employee has already entered; & 3) Send all subsequent emails to both Customer & Employee to confirm Appointment, with working Hyperlinks in the emails. DocMusic is a music-based company focused on a dj-listener experience, using playlists & private 1-on-1- consultation as a medium.
We pay fairly & on time, using PayPal.
We've provided a very informative visual aid to show our current site features, & what we're missing.
Please review it carefully when estimating the Scope, Budget & your timetable for completion.
Thanks! Looking forward to talking to you.
