When you say "I made a lot of money for that company" do you really mean that "you did alot of work for that company"??
The fact is that THEY ponied up for building a store, buying printers and equipment, materials and supplies, advertising and marketing, insurance, computer equipment, software, etc.... All before they ever made a nickel selling a sign.
Just because you squeegeed the decal on the substrate IS NOT the same thing as "making them alot of money". They make alot of money because they have a good business plan, and are well capitalized, and (until recently) have good employees. You were just ONE small component of how they made money...
How are you going to do all the OTHER things involved in running a business that they do.
Its the same thing as a cook in someone elses restaurant muttering about how he does all the work and the owner is making all the money.
Now he quits, and says "I can't afford a kitchen, but I am sure I can sell food... does anyone know who I can get to cook food for me until I can get a skillet??"
Sounds silly, doesn't it.
If you don't have a printer, or any equipment... and you don't have (or cant borrow) a big wad of money... then the only thing YOU actually will be doing is selling and maybe doing layout design. The catch is that if you don't do alot of selling then you have nothing to design! So the nuts is that you are suddenly now an outside sales person.
Did you do outside sales at FDEX/KNKOS??
You CAN make it... but you have to understand that you can't sit at home waiting for the phone to ring. You have to get up every day (just like a lion in the Africa) and go out and start chasing gazelles (customers) or you will not eat tonight!
Think about your original post...
You didn't MAKE them alot of money. NOPE!! You COST them alot of money. Employees are overhead and an expense item. They MADE money by building a business model that generates SALES. Whether YOU were there or not had ZERO impact on whether they made money. In fact, you've been gone a while now and I bet they are still in business.
I am not bashing you.. I want you to be successful, and actually running and managing the business is the hard part NOT printing the decals and designing banners.
For my positive contribution..
I recommend a Mutoh Valuejet 1600 series, and a 24" graphtec CE5000, and a big squeegee or two. Get a BIG smooth work table. If you have to job out prints I suggest a relationship with any of the wholesale vendors here, but also a couple LOCAL sources when you need a quick turnaround. Identify who your suppliers are going to be. Set your prices HIGHER than FDX.
