Trademark

Hi everyone,

I’m a small business owner looking for advice on trademarking. I’m considering creating sub-brands under my company and want to make sure I approach this correctly.

Should I trademark the parent company name, each individual sub-brand, or both? Also, has anyone here gone through a third party for the trademarking process? What was your experience like? what’s a realistic ballpark figure I should expect to pay for this service?

Thanks in advance for your insights!
