existing form fields data to database with newsletter capability

Hi everyone, I have a website at [login to view URL] it has 3 forms that send data via email to a specific email address, 2 of the forms are identical, the forms are listed below along with their locations: [login to view URL] [login to view URL] these 2 forms are indentical at present. [login to view URL] this is a seperate form requesting to purchase new cartridges. What I need is for the form data in all fields to be added to a database but still emailed (as they do now), the database needs to be searchable by all fields, have a login for admin to view data and download either all content to a csv (excel) spreadsheet or parts of the database, there also needs the capability to be able to send out a newsletter to a single entry, certain chosen entries or all in the database, nothing too fancy, just that really, think it might be wise to seperate the forms that are used on the website into categories in the database [login to view URL] a collection section, purchase new cartridge section and enquiries section which comes from the contact us form, this way if a newsletter has to be sent then maybe admin could just choose (if they want to) a specific category? ftp and cpanel access will obviously be given to the freelancer who does the project, many thanks for looking, any questions then please ask
