Hey there,
I understand that you're looking to create Softaculous package for custom Opencart installation. I am glad that you are pleased with the results of the auto installation. So, I have been in the development space for about 8 years and I have worked on lots of Opencart projects.
I have great ratings, feedback & work history, so I assure you that you're in the right hands. If you have any questions or concerns, please let me know.
Sincerely,
