Joomla Developer

We currently have a Mailchimp mailing list. We will shortly be launching a new company where folk will purchase places on choral workshops. At the moment we use TicketSource to sell those tickets. We are also developing an online questionnaire that will determine which of the workshops an individual is best suited for, from which contact information can be gathered. We will also have an online opportunity for folk to join our mailing list. We therefore have 4 sources (and manual entry a 5th) of contact data and we would like that all captured in one place so that it can be used for future mailing and possible entry into and back-end membership area. Ideally this would be achieved within the Joomla back-end.
