Hourly rate is $100 USD. There's no minimal project size, so if it's quick fix(es) - it might be just $30 - $60, so you won't need to pay for the full hour in such case.

Usually - right after the payment is made, unless I'm working on some big project at the moment, but in most cases I start immediately.

I offer a lifetime warranty for all customizations made, unless you or someone else make any changes afterwards (code edits, new apps installations) which cause conflicts - in such cases additional work is required, and it's not caused by any code error. If you notice any issue caused by the changes I made - I'll fix it for no additional price.

Themes customizations of all kinds: visual edits, custom sections/blocks, accordions, tabs, pop-ups, infinite scroll, quick add, subscriptions widget, product personalization, related products swatches, linking images to variants, upsells, quizzes, bundles, progress bars, free gifts and so on.
