Symfony2: sonata admin multiple file upload

Estimated duration: 2
Description: I'm a student actually working on a symfony2 project of my own (my personal portfolio).

There are few things I need to understand. I'm the kind of guy who can't just copy and paste.. Well, I would be happy to find someone who can help me to:

make me understand how to handle multiple file uploads with the sonata admin bundle, and I have also few questions about doctrine and how to work with the repositories. I don't think it's something really hard to achieve for someone who is used to work with the framework.

Ideally, I would like us to meet, and have someone next to me who can explain me what is wrong and why it's wrong. Someone who can also teach me few things in the same time.

If it's not possible to meet we can also think about other ways to achieve it like skype/gmail chat or whatever. In this case, you will maybe have to write some code before we take a moment for you to explain it to me.

I would be very grateful if you accept my request.

Best regards
