Hello,
I would love to help you with your project.
In all honesty this sounds like quite a simple task, and I imagine it would just require a few tweaks to your existing website.
Would you be able to provide me with a link that currently has your products that lack the scroll functionality?
I'm new to the freelancer.com venue, as such my profile is really lacking things that might make my bid stand out, nonetheless I sincerely hope you take my proposal into consideration.
Best of wishes,
jeanfdehaerne
