I'm building a website for an au pair agency business that will connect au pairs to families around Europe. I know nothing about website building, HTML etc. so I'm using a wysiwyg editer (weebly). How I would like the site to function:

• Families upload their information into profiles
• Au pairs do the same
• families can view a limited part of an au pairs' profile until they pay a deposit
• After deposit is payed, all au pairs' profile information becomes open to families
• Families can order au pairs and confirm their order with another payment
• payment must be made before 'order' is confirmed
• By 'order' I mean full communications become open between the family and the au pair they have 'ordered' as well as travel information being sent to another agency
• the site needs to be linked with a bank account (e.g paypal) and another agency, who will look after the flight bookings etc.

A website already exists for this business however it just contains information on the business and application forms - if the site becomes fully automated it will relieve a lot of strain on administration in the office (dealing with applications, travel information etc.)
