Hi Chris,
I'd be happy to help with this. No need for payment. Maintaining feedstock like this is an ongoing process and getting he recipes onto conda-forge in the first place isn't the hardest part. That should be particularly true in this case because it appears that all these packages are available on PyPI already. There's a tool called grayskull (maybe you know about it already) that should make the transition quite easy, especially given that you also already have your own conda recipes.
It seems like the starting point would be to add recipes for the packages you need that don't depend on other packages. Having had a quick look at all the recipes for the packages you listed in you email, it seems these are the ones to start with:
bw_processing (not listed but a dependency of listed packages)
constructive_geometries
stats_arrays
Are there any that I missed?
I'll go ahead and make recipes for these 3 and include you as a maintainer, and we'll work from there.
Cheers,
Xylar
