Analysis of the online store, development of a new

You need to analyze the existing online store (written to order a year ago and while developing in general, good, but want even better). If necessary, make improvements in terms of convenience and output in the top 10 in the Irkutsk region. You need a mobile version of the store and the entire site. If from the point of view of the auditor you need to switch to another engine and carry out a complete rework, improve the design - the proposal will be considered. I'm waiting for commercial offers.
