username & password and forms

Hi, I would need the following for my website which has html pages (no database, php etc.): 1) a) access from menu for accommodation owners with own choice of username and password in order to change data on individual html page (update rates, information, upload a photo etc.). Individual page exists in English, Spanish and most also have it in German. b) for each page changed by an owner, I need a notification regarding the details before update is published in website. Please forward your ideas on this point. 2) from clients I receive through the website a form (in one of the 3 languages) regarding request for accommodation. If possible I would like the following: a) automatic response to the client with an e-mail through Outlook or webmail, which contains in the subject line some of the information within the form received, namely: name of accommodation, arrival and departure date. It should also show name of my website. In the body a general text. b) forward form onto e-mail of accommodation with less information as received (without e-mail of client, telephone number in case indicated) c) form check if given dates are possible I would need a separate budget for point 1 and 2 and will give the job to someone who can invoice (I am in Spain).
