Depends how well the 32x32 basicset will sell in the next month(s) as it's super time intensive to make higher res versions.
If you need specific icons and in a short amount of time, however don't hesitate to contact me via E-Mail (thomas.feichtmeir@gmx.at) and maybe we can agree on a handful, as just upscaling a bunch is way easier than upscaling all and would make a good commission.
