Hi David newbie here as well, what sort of equipment you got, also any connections contacts from past business you could use, every tradesmen needs a sign, how are you with tools like photoshop corel or adobe illustrator
I found so far its easy enough to buy equipment and tools etc, business side thou is another story, every town/city etc have their own shops that have good long standing record so your new to all this, only advantage is you could do it cheaper, thou again requires a lot of practice as you can fit a lot into vinyl roll or waste half on simple work, first get some different materials to get grip for them,every vinyl is different ive still no clue on oracal numbers, but only way to learn is to make mistakes, get some spare vinyl design type cut weed rinse repeat, age isn't important its getting connections training and doing work to see how it comes out, Ive got myself needed machinery software, even business training course but last two months my plotter been idle ive been flicking with designs, website, networking and my brains just wont pull it,seems a lot to do but suddenly reality and motivation is down.As came to realize networking and advertising is a proper clutch - as im not really social media type person, nor door to door caller,anyway thats my issue, dont want to bum you out just my story here. Software is easy enough to learn, communications at your age could actually be a benefit any contacts you might have or know as even small jobs will give you practice. I know some say try it out in some sign shop but reality is many who do well wont take you or let you near equipment that could possibly go into 4 digits easily but if works worth a try just to see how pros do it.
Id say get diff mobile number that would be easy to remember name your company, even if you dont have a site print some signs on your best car/truck nothing fancy just do signs need a sign, would be my advice once you cant do some simple lettering jobs and some design, in other words take it easy but do your research and learning, its not business type where you get busy just because you got equipment.GL
