Custom work PrestaShop

Hello, I need some help configuring and modifying PrestaShop installation (1.6.1.9). I have installed and configured most basis options/modules, and also purchased and installed some extra addons for which I will need some help. I need an PrestaShop EXPERT to help me finish the Shop. An expert, meaning having lots of experience in PrestaShop. I also need the freelancer to have a high rating, at least 100 good reviews. I will not describe all the work here. It is too much. I will check all freelancers carefully, maybe ask some questions, to come to a descision who to trust for this. Thank you
