Need professional help upgrading from 1.1.8 to latest version

[classicer]

Hello Everyone,

I need developer help upgrading from early AbanteCart version 1.1.8 up to the latest version while preserving Global Attributes functional for finger size and Google Base extension. Currently there are about 200 jewelry products. We are hosted at SiteGround cloud account. I will provide login credentials and will gladly compensate for your support to make sure it is upgraded professionally.

Waiting for response, thank you!

Best,
Gnel
