I have a pretty big fab shop now but early on I did a lot of internet advertising on Craigslist mainly. You'd need to do FB marketplace nowadays but you can copy/paste to CL.
I'm on instagram and actually prefer it...but most stuff comes through FB...I have my IG linked up to post on FB. @rlcweldfab is my Instagram. Follow me Lol. Non bumper site is
www.rlcwelding.com
A lot of small time welders have horrible FB and CL listings with horrible pictures. It's literally free. Spend some time making good listings, then you can refresh them once a week. Good pictures, no misspelt words, your contact info. Get some help with the proofreading. You can buy stock photos for pennies.
Make 8 ads on FB marketplace.
2 for welding.
2 for repair
3 for products you'd like to make
1 off the wall related service.
Since I have a fab shop I put an ad on for metal sales...sell by the pc. get the markup that metal supermarkets has (i.e. 50-100%) (it will still be cheaper than Lowe
s) You'll sell some metal and meet some people.
Custom fire pits, patio furniture repair, handrail repair, custom mailbox posts, trailer ramps, trailer modify and repair, dumpster repair, ladder racks, can all be individual ads and they can go in different catergories.
And people will respond with I don't need that but I need this...
I started with off road bumpers and I still make them, but early on in my garage I put a CL ad stating I would make any bumper for any truck for something crazy low back then...like $250. But I got experience and had some pictures of my work, and eventually some repeatable products.
Good luck!
