Plug In For Wix Designed Website

Based in South Africa... [login to view URL] is a non-profit dementia start up organisation to help and support people living with dementia and alzheimers. We want to add the following plug in: A Searchable directory for: a. Care Homes b. Caregiver Placement Agencies c. Caregiver Training Institutions d. Private Caregivers. Think it should at least be searchable by Category, Area, Post Code (linked with google maps addresses), Specialty Populatable template by service providers or individuals (content, images, etc), which requires approval to go live. Service to organisations and individuals wanting to list their services would be chargeable so would be great if they can transact online?????? to do so but baby steps are fine. Would like to have ability to offer memberships along the lines of: 3 months = x value in ZAR currency. 6 months = x value in ZAR currency. 12 months = x value in ZAR currency. Our ideal wish list is for someone to do us a pro-bono project, recreating the wix site we have designed in wordpress with the above plug in PLUS other features would would help us, such as a retail shop option so we can try and sell dementia / alzheimers and age related products. Thank you with sincerest gratitude from the DROP team.
