I guess you haven’t worked professionally with clients before, because professional business communication doesn’t always happen publicly in comment sections. Portfolios, rates, and project details are often shared through business emails or private messages.
You seem to be confusing a professional outreach message with a public portfolio post. Perhaps you’re still new to the industry yourself, so I’d suggest learning how professional commissions actually work before lecturing others about them.
Anyway, take care, and good luck with your artwork. I hope you find enough work to keep you busy, too.
