MFC Bug fixing and changes

We have an MFC project currently running at around 10K lines of Logical code, about 24K lines of Physical code. We are looking for someone to help bug fix the project in its final stages. A good knowledge of MFC is essential, we use a bug tracker and Subversion for source control. I estimate each bug would take around 30 minutes to fix. I suggest the work is currently quoted on a per bug basis which can be adjusted later. Please quote for 30 bugs, obviously if they take longer than the average 30 minutes each we can discus either a bonus or another project.
