If you do not have the money then you are not prepared to sell the product. It would be like "I want to open a bakery but don't have the money for dough". Inkjet ink will fade in literally weeks, it will not work for any form of sign/graphic work.
If you are just trying to start small, look into getting a loan on a BN20 as it's a great starter machine.
You cannot use a tabletop laserjet to print wrap or sign vinyl.
He was not talking about inkjet ink here. He was asking about fused toner (LASERJET) which will last an amazing long time compared to aqueous ink.
Your alternative is to sub out your print work to someone who has the correct machines to do just that. You cannot use a tabletop laserjet to print wrap or sign vinyl. You might be able to find a used wide format for a decent price, then purchase the software to print registration marks on your print job so you can run it through the Graphtec. That is, of course, assuming that the Graphtec is capable of identifying registration marks. If not, then you're still at square one. Sub the jobs out.
Whats insane is your narrow mindedness.
