Hi Sir,
We are a team of 4 members having 4+ years experience in magento and its complex solutions like product import, upgrade,etc.
As we have worked on bug fixes and has experience in handling serve, we can serve you better and make your site run properly. And we can be your long term webmasters.
As we don't have any idea on what is the issue and how much work involved, we plaved our bd=id for minimum amount. We shall discuss the work to be done and finalize the quote. If the work is less, we will work for less than the amount we bid.
Thanks
