PHP email attachment

UK BASED FREELANCERS ONLY. I have already designed a working PHP form (click on "send me more information"): [login to view URL] When the user selects the "email me a brochure" checkbox I need a PHP script added to my existing script which will attach a .pdf file to a HTML email, with absolute image references, and send it to the users email address. I will provide the HTML page and image references. Email me and I will send you the 2 existing PHP files. 1. Should I use embedded images for the HTML email? 2. Can I also include a text version of the email body? Can you give me a quote for this work and a timescale. Payment will be via a direct BACS transfer.
