Hi
On the experience and expertise standard of my company I will prefer to go with latest version of Photoshop. This is inexpensive & best to handle with its smallest servicing price.
I believe, we are the best suited company to provide this solution you are looking for, and that will not only be speed optimized but also full custom designed.
Below you will find my concepts to bring out the remedy you search for.
Thanks and Regards
