Hello. I have extensive experience in converting PDF files to other formats. I have converted over 100,000 files for a client in the US. I tested many conversion apps and found one that stands out above all others, so I can give you the best results currently possible. Let me know what file type you want: DOCX, RTF, TXT...
I can convert several thousand files per hour, so I expect your files can be ready in 1 day.
If you would like to see a sample, send me a file or a link to it and I will return the converted file to you.
