Os Commerce shop programming in multistore solution

Task: I'm looking for someone who can expand my OS Commerce shop into a multistore solution. I will accompany you through the different stages of programming and work on it 1: 1 with you. That's exactly what it's about - Transfer of the old files (stored in DB) assignment of the articles and folders via the dropdown menu to the respective shop (setting option in the backend) - In the case of newly created articles, it must be possible to assign the article to a shop without the other shops showing it. - Texts such as imprint, contact etc ... should all remain the same - Logos and front-end settings of the respective shop must remain separately adjustable! - Payments should all be assigned to one shop (possibly via the dropdown menu to which shop it should be forwarded) - When installing the update, you should be asked whether it is the parent shop or a shop extension. - Box positioning in the front end with size, color etc ... - Revise shop installer Dashborad: - List of installed shops that access the mother database - Ability to deactivate shops - Monitoring of the shops - Possibility to copy the shop including data that have been selected for this shop. (Download option including installer, database and shop system. Fields such as bank details, imprint, contact must remain empty, license key should be active) - List of licenses Security: - License key generator (to be generated by the parent shop) - License key system for the shops that communicate with the mother database. (as soon as a key has been generated, a mail should be sent to me to be approved) The following options should be available in the license key system: - Period of time for which the key is active - Number of data records adjustable - Enable and disable possibility - Repair / repair SQL INJECTION check if necessary Field extension (backend): - Google Adsense input option - Google Analytics input option - Google FTP password generated - Fb pixel input option - Instagram input option - Microsoft input option Aim: The aim should be, when a new domain is bought, that a new shop can be installed in simple steps and that this connects to the mother database, automatically reads in and publishes the data for this shop. A shop should be able to administer x shops. Furthermore, if someone wants to buy a shop, it should be possible to purchase it with a license system. Miscellaneous: I expect that all data, updates etc. will be programmed without encryption, hidden spamware etc. All copyrights go after the work is finished and paid to me automatically without exception. If you bid on this project, I expect a fair price. Renegotiations, price changes will not be accepted!
