PHP programmer to refine the site

We need to refine the site on the old Shop-Script engine. The engine has already been deeply redesigned, made adaptive design, added 100-no changes. Its working. But there is a list of a number of additional improvements that need to be made. I will send the list later, after selecting the artist.

Looking for a good PHP programmer, ready to pay for it. Ideally 1 full day a week, because on this day I too should be in touch to coordinate the work as they are completed.

Write the cost of your days work, the rest I will look at already in your portfolio. Assessment of the work will be made by an experienced, but very busy programmer, so without a lot of experience and without professional knowledge I ask not to write - lets save each others time. Thank you.
