Joomla CB and AdsManager - Very Small Modifications

Hi there, We have Joomla Site with CB and Ads Manager Components already installed and working. We need 5 small changes made as listed below. 1- Adsmanager component: A) In the list of ads, We need to show the CB avatar of the poster (user), currently is only showing the username of the poster, so We need to also show its avatar. B) We need to have a date field, currently We have just created a text field where users inserts a date such 12/24/2007 MANUALLY, but We need it to be more easy, and have it to choose maybe from a small calendar or something like that (maybe a drop down dates) also work. C) The expiration of the ads, is implemented originally, but for some reason it doesn't work, We Need to have it fixed. And must be working with the DATE FIELD above, not with the DATE OF POSTING. *********************** 2- COMMUNITY BUILDER: D) We have created country field (list of countries) for registration, but need it to show an extra field with a list of states depending of which country the user has selected above. For example, if someone choose 'Australia', then automatically show a new field with the list of 'Australian States'. If someone choose 'Canada', it automatically shows the 'Canadian States'... and so on... E) Any idea on how to have the users insert their birthDATE, when registration. And then have their age automatically growing every year? Currently I have created a drop down field with ages from 18 to 99, but they stay always like that, the users never seams to grow in age Please bid to do the above, should not take too long for capable programmer with Joomla Knowledge. Budget is low, bid low and win this job ! Thank you !
