if you're not that strong on php coding you might it difficult to:
create script that allows you to upload a file
check it's integrity
then send it off as an email attachment
that's the basic theory of it but to support verizon you have to do more than that as they operate a pretty tough walled garden policy and often enough block downloads and certain mime types in email attachments.
as for something that is ready made, well i've made a wap push, wap download and verizon deployment solution but it's commercial work so i can't show the code online. there are a load of php scripts for file uploads and loads for emailing a file off. you'll have to put them together.
