Don't get too disheartened from the feedback you have received so far, through the guidance you will receive in this forum you will end up with a logo worthy of representing your new company, but at the moment it's still not there.
If I was you I would start from scratch, brainstorm what the company does/offers. Look at how the vinyl signs are produced how the vinyl arrives etc... You have mentioned previously that this is your passion so should be able to come up with a lot of primary research and concepts. Through good research and development a good idea will arrive.
Look at other companies and their branding/logos to get a feel for how yours should look, but not to copy!
