Regarding the project, yes there has been changes in Obtaining Consent with the User Messaging Platform. I believe you already have a valid ANE from distriqt. I should be plenty of help for this project. Sorry, I need to go little above your budget, but that is a justifiable price for the work.
Let me know if you have any questions.
Regards
