Other minor fixes as required To show you have read my bid, please put “magento pro” as the subject. Provide URLs of 3 magento websites you have worked on. This is a live site so all care will need to be taken to ensure site is not down. The last contractor messed up my site, so if you can’t delivery then don’t bid. Only want skilled professional workers, if you delay or don’t delivery, payment will not be made. As I wasted months with last developer. Answer the following questions when submitting a proposal: How long have you worked on Magento? How many sites have you built to date? Do you work alone or with a team? Please confirm costs and time scales. Thanks
