@kayliart - So nice to hear that your shirt business is growing so fast. 40 shirt designs a day? Wow - I can not even do 40 doodles a day !!
I can imagine the workload. Also - when something has to be done as a business and as a regular routine, though creativity is involved, tasks start seeming boring.
Perhaps you can think of outsourcing the research and upload material prep part though the actual uploading of that information, which the outsourced agency will get ready for you, will be totally in your hands.

Hope you find the correct work-life balance in your busy business routine. I am quite selfish in saying this since I will, then, get to see more of your lovely sketches of anime girls! Also - as a by product, you may find time to provide feedback on my blogs. LOL. Just kidding.
Have a great day. Cheers. Upvoted.

Regards,
