Will Pay for help fixing PDO_ODBC bugs

I have two or three bugs in PDO_ODBC that are preventing me from utilizing it fully.

1) queries with bound parameters in subqueries fail. (php bug #36561)
2) Unicode fields from SQL Server get chopped in half when returned from PDO_ODBC
3) Fields greater than 128 characters long have to be the last fields in a SELECT statement or everything after it gets returned as null. (I think this is fixed in the latest version, but I'm stuck on an old version with a branched fix for issue #2)

I need someone who can fix these problems and get the changes committed to the CVS so they will be fixed in future versions. Do you have the skills and time to do this? Let me know your rate and a rough estimate of time involved if you can.

Thanks!
