We wish to have a 3-layer web system built which is based on a catalogue of opportunities (discrete items and collections) which a registered client 'agrees to buy', they then receive an email confo of what they have bought, totaled with some preset T&C's - similar to a shop front end. At at the same time advises a regional area admin (one of 5 dependent on the client's area) who curates the sale with the client(s), mostly manual recording of steps, readies the information for us, and lastly we admin the item(s) and record progress. System records progress/status (not visible to client) from a common view.
System email action is only required at account creation and at 'shop' buy. No money changes hands in shop it is all by invoice.
CMS frontend/MySQL back-end preferred. System will be cloud based.
