Hi, i have read your project description and checked the examples, i understand what you want and i would like to offer you my services. I have excellent knowledge of Magento and related technologies, plenty of experience with them, most importantly including experience with creating various complex modules (including very similar to this one), so i can finish this project quickly and to your full satisfaction. If you would like to discuss the project details, feel free to contact me by private message. I'm looking forward to our cooperation. PS: The budget $250 is not enough, $500 is more accurate.
