I work in a huge shop, were talking 40,000 sqft just for the warehouse portion. But I have my own setup at home as well.
At home I mainly do online, rarely sell to anyone local - 3000 sqft townhouse, printers in my garage, graphtec / laminator and everything else in my basement.
I'm currently looking to move my home shop elsewhere - the cheapest I can find a shop that's equivalent to my current setup is 6k a month, just in rent. Anything with a bay door for wraps / graphics is 7-8k.
Dropping an extra 1k, if you can afford it is a no brainer!
At home everytime I switch a roll of laminate out, I hit the ceiling. Everytime I want to relax... I feel obligated to rush an order. I hate bringing people here to see samples, or pickup product. I want to grow with more equipment... But no space. It's a side hustle, so dropping so much on it won't happen until Im ready to quit my full time print job, or I absolutely need the space.
But I can say I'm happier to work at a real shop then I am at my place - work where your comfortable... If you're miserable where you are, soon you'll be miserable with your company and want to give up.
And the opposite stands true too - One of the biggest advantages a salesman can have is confidence. So moving into a new place that makes you more comfortable and confident in bringing clients around will likely get you more work, and more sales.
I say if you can afford it, and have a little bit of a rainy day fund to keep you afloat incase the worst happens... pull the trigger.
