Modify Joomla Components

I need an experienced programmer to help update and modify a custom CRM Joomla Component. It works quite well, though there has been some bugs that popped up with software version updates. Updates to CRM: - Emails are sent to default domain users (when a user doesn't have an email, a fake @[login to view URL] is created. There is not supposed to be an email sent, but it is) - Would like to automatically generate domain name for function above (bonus) - When a contact is updated, an email is sent out with a new password. The new password doesn't work. I do not want emails sent after the initial creation of account - Occasionally users get hung up (i.e.: user 'Sam' can't have any additional information saved. I tried to add address, etc but it's not saved.) - Default password should be updated to 6 characters including letters - Update installer to create required tables if they don't exist (uses virtuemart table & custom CRM table)? - Need to edit accompanying ccInvoices file so contacts update There are a couple more projects that need worked on to - once this is complete I will hire you again for the other projects.
