Payed Help to make Single Stock Attributes (2.1.0) 1.7 module 100% compatible with Prestashop 8.1.7

[Aupino]

Now again.. since prestashop 1.4 Single Stock Attributes been my biggest headache every time I had to upgrade to a newer version.

Now i want to upgrade my 1.7.7.8 site to 8.1.7 and the module i need to use Single Stock Attributes (2.1.0) by Presto-Changeo does not have a prestashop 8 version. 

I Don`t now how mutch need to be change, but it must run 100% With out any Warnings.

Any one who can do the fix  or other module who do the same please give me a Quote..
