Create online database/webpage

I need to create a webpage where clients and client-advisors can log on/create profile and update/write information about their clients/business. After the information is updated/submitted an email will be automatically sent to the designated business advisor and the business -> giving notice that the business information has been updated/created. Each company can choose a designated advisor from a list in the business information that will be defined as their business advisor. Each business-advisor, when logged on, must have access to all their designated business-profiles, and be able to view/update/delete the information. An administrative profile must be able to log in, but only see the number of active business profiles. There must also be an option where this administrative profile can print a list over (only) the names and the date when the business profile was made (for billing purposes). There must be a \"forgotten password\" application that is fully automatic. There must be an option where a business advisor can export business information to excel. Finally. If the business information is not changed or updated the last 11 months, a mail will automatically be sent to the business. If the business has not changed or updated the last 12 months an email will automatically be sent to the business advisor. I can draft up all content and design (minimalistic) so it can serve as a blueprint. A brief description about safety in relation to keeping the business information safe online must also be submitted. Looking forward to see an easy and minimalistic webpage. Best regards Arne
