Hi,
We are a Los Angeles based web development firm, specializing in Magento. We are new on Freelancer.com, but we have established profiles and history on other similar websites.
I can fix this error for you within one day. One way to fix it is to install Magento's database repair tool.
If it is something to do with 3rd party extensions, I can try to fix the extension, if it's relatively simple, otherwise you will need to contact extension developers.
I will be happy to answer any question you might have and I appreciate your time to look through my proposal.
Best regards,
Alex
