WooCommerce Expert- estore


I am looking for a quote- or at least a range for the following type of woocommerce assistance:

-Transfer existing e-commerce (woocommerce) store to a NEW theme.
(Redesign the woocommerce layouts to accommodate the latest build)
-Plugins, a little development to make sure it looks the way we need it.
-The ability to test it/look through it and adjust a few items
-A small amount of patience.

Our e-site has a theme that is no longer supported. When the big update happened earlier this year, it broke the site.
I hired a freelance developer to help get us back running, now the site is fragile.
I did not create this site.

We have all content, products, graphics.
We have approx 400+ products, but would add much more after the site is stable.

I look forward to your reply.
Best Regards,
Marketing Manager
