welcome to signs101!
ask away!
viable? ...yes, we seem to think so
At least you are working in a successful(?) shop already which is an excellent step that a lot of new entrepreneur's arriving here have not done, and you mention "research" which is a good sign.
It seems that more & more folks pop up thinking it is a cakewalk/gravytrain (hmmm, not a tasty sounding choice of words together) ...but although it is not lowhanging fruit waiting for the lucky few to discover... it is an excellent career if you lovethe work. because there are a lot of worse jobs out there.
Speaking of jobs... in the sign business... there are two distinct things going on... signs... and business. You need to be good at both, & constantly striving to become better at both. If you can do that & you can enjoy doing that... go for it.
Like most business's you will want to plan on lots of long hours & possibly years of building up to a plateau where the monetary rewards begin to exceed those you could realize as an employee. If you havethe energy to take that on at 50... more power to you. I'll be 48 in 3 weeks & am celebrating my 10th anniversary in business. I still work 60 - 70 hours though & work on ladders, with power tools... carting heavy boards around... I've enjoyed having an employee who does more of that then I do now... but I did it all myself for 8 years & I'm not sure I'd want to do quite as much in the next 10 years.
I think the main thing I'm saying is, if you know what the "business' side of any business requires of you... beyond the 40 hour week of just making signs... then you will have a good idea of weather or not you will enjoy this career.
If you are not really cognisant of all that will be required outside of making signs... be forewarned, the business side of the sign business will consume a huge amount of your time in order to be successful. If you're lucky, you will enjoy that as much as you enjoy the sign part, like I do. Then you won't mind the long hours & yes, it is a viable career. I feel very well compensated for my long hours this year... on top of enjoying most of those hours... but it does take time to build up to feeling well compensated. The first several years it was only worth working thathardbecause I believed I would someday arrive at where I finally arrived, in terms of earnings.
