php sql simple mailing list

I am looking for a simple text box on my website that will allow users to add there email address to our mailing list. they need to be able to select if they are interested in; Sewing Skills Quilting Machine Embroidery Everything - Remove email (this will delete that email from list.) i then need a page that displays all the email addresses separated by a comma. on this page if i click the create email from the group name (Sewing skills) a email will be created with all the people that have selected that option and the everything option to populated in the BCC section of the email. for security this page needs to not be crawled by search engine. this is a very simple project so we have a max limit of $60 for a quick turnarround
