569520 Genealogy website

I would like a Genealogy webiste. I also need a forum in it. I'm thinking that a CMS like Joomla or Drupal or any that you are best working with, would be ok. I have seen genealogy websites using PhpNuke and Joomla and Drupal. Most all CMS has forum modules integrated in so thats not a problem. Also, I want a payment system and most CMS has this as well. The hard part is making a pedigree tree, but this may not be hard, as most CMS have menu tree modules or some sort of parent/sibling module. I need all this in the script or CMS. I do have a idea on how the layout should be. Please reply with fair quotes on price and time needed to develop.
