I'm currently working on migrating content on hicksdesign.co.uk over to Statamic - it's been running Textpattern for 16 years now! :o

I found a handy script to output blog entries as markdown files:

https://github.com/cole007/textpattern-statamic

but it doesn't support custom fields created in Textpattern. Does anyone know of an updated version? Or have the skills to adapt the script and can help out (paid of course)?
