Hi there,
Thanks for this opportunity! I have 14+ years of experience in Web development and after reading your requirements I'm 101% confident I can help you with your task. In fact, just to test my programming knowledge, you can throw any kind of problem at me right now (not necessarily related to your project) and I'll solve it for you.
Now, in regards to your project, I think it's best to create a separate plugin that will use hooks from the aggregator plugin to do what you want and if there are not hooks available, I will use a technique called "code injection", more exactly I'll force the plugin to work with my code.
When you choose to work with me, you get a partner that actually responds to messages/emails/calls, gets things done and is committed to helping you succeed. Just in case you need a fancy or professional design (for this project or for another one), I got you covered with that as well as I have a super talented designer that I collaborate with.
Moreover, my english is great so you can be sure that there will be no language barriers.
When you're available, let's discuss your requirements in detail and if we decide we're both on the same page, we will then take it further and get this done ASAP.
Looking forward to helping your reach your goals and build a great business relationship.
Regards,
-CR
