We have had a Magento site (ver. 18.104.22.168 CE) running smoothly for over 6 months and prior to Christmas added some extensions. Since then we have had ongoing issues. We after a programmer than can, 1) fix the errors and make site stable again. 2) install the new extension properly. 3) optimize our site so it runs faster. 4) Clean up store incorrect/wrong unsecure/secure broken links and unused file etc. 5) general overhaul. Once we have achieved this we will look at new projects. SEO, CC and migration to new version.
