Interspire Email Marketer Sendgrid API Bonce Integration

Very Very Simple project... it has already been developed but i cant seem to track down the developer. I have many setups of Interspire Email Marketer, latest commercial version all running from SendGrid via smtp Now all i need is a simple module that can be installed and can ask for API key and can process the bounce, will use the bounce cron built-into interspire. Needs to be admin only, but needs to process the bounce for all the users (clients) that i have setup, tons of work of this kind available to the right users. Note: Limited Budget Many Thanks, Vincent
