I am experienced Linux system and database administrator. I have extensive experience with handling big data (however, yours are not that big). Anyway I need initial milestone just for using my resources (transfer, disk). I can't tell if your data is broken, or your system just can't handle data this site or you have some other trivial issues. As far as I can get it and this is really valid SQL I can deliver it back to you in any format you want. If it is broken I'm able to analyze it and tell you why. Also I'm able to recover valid parts of SQL and get them back to you. However if recovery would require much more effort I'll ask for separate project for complex recovery.
