So after doing a little research I came across a tool that supports for reading and saving all release versions of DBC, DB2, WDB, ADB and DBCache of Blizzard's client db files. And it in C#, so we can either convert it to C++ variant or work with it as a wrapper tool.
I have intermediate-level knowledge and experience in C/C++. BTW the bid price is just a place holder, we will discuss that later.
If you like my proposal than we can discuss about the project in more detail. Looking forward to working with you.
