gravity forms wordpress plugin

Avg Bid (USD)
Project Budget (USD)
$10 - $30

Project Description:
I am creating a classifieds website. I do NOT want users to have to sign in.
I am using gravity forms and I am allowing users to submit a post into draft state.
the problem is they have no way of editing or deleting their post.

there is an update post extension that should make this a bit easier!

essentially i want to store a code in a custom field and then, after a user fills out the 'create classified post' form, they get an email with a private link with that code in it, the plugin/function should check the variable in the url (substring) and see if it matches the posts custom field. If it does they should be allowed to edit or delete the post.
I am having trouble and am willing to pay for help!
It should not be that hard I dont think
