SugarCRM Contact module

I am looking for someone who has working experience with SugarCRM and module creation. I don’t have time to explain about SugarCRM and how it works so only people who have working examples of SugarCRM modules etc. need to post. I need the contact section of SugarCRM to provide us the ability to create contact groups and then create contacts within that group or assign contacts to the created groups. Then through the email module we should be able to select a group to send the email out to each contact in that group or only selected contacts within that group. If through your past experience with SugarCRM you feel you can accomplish this project Monday, July 10th then please feel free to lease a post below.
