CMS installation, modification, Maybe Joomla..

the association is SKAL international (Phuket)The website is [login to view URL] What we need is for members (about 90) to be able to access a section on the website using a password/membership number to put their business details and promote their business. The section I envisage would basically have the following fields: - Business name - Contact name/SKAL member - Contact numbers - Address - Industry/type of business - Description of business - Current promotions - Special promotions to SKAL members and friends only - SKAL member since - Notes/remarks We would also need to be able to set up new members that join (by giving them a password ( which you/us (if we know how to do) would then set up to also give them access. Vice versa for departing members We also want to set up a newsletter template that we can update ourselves every month (in a very simple way) Hope it makes sense….if so it would be great if you could pls give me an estimate of costs ALSO: I have an SQL access DB which I used in my previous business …the DB was saved on an Exchange server (and I believe a special SQL server). I copied everything before I left the business in OZ and now trying to restore here on my computer but seem unable to (get some error messages re not being an exchange server or something along those lines)…so I’m just trying to restore the database so I can use it again…any ideas of what’s involved/costs?
