Hi, I am an experience website manager , with over 50 projects handled and comfortable with kind of content you have mentioned.
I have used open source softwares for making postings, submissions etc. but never used chameleon earlier. However, it will not take much time to understand the software.
I can easily create the required galleries everyday. I have personallised business broadband width so the upload will be faster for fast output. Moreover , I have 3 data entry specialist in my onsite team , all males so they can handle the project very easily.
Willing to work for a longer period. You can check my feedback for the accuracy and quality that I maintain for my projects.
I am not sure about the load of project so here I am bidding for a week's work or 30-40 galleries creation.
Thanks
