I am a web content creator. I am not good at design, legal issues, etc. I imagine I'm not the only one.
I wish you had professional service listings:
- web design
- consultants (business, advertising)
- legal services (the is the best place on the web to
advertise legal services to webmasters, right?)
- accountants specialized in our field
- angel investors/VCs
I recommend charging monthly, not "per ad".
Only real professionals that seem to have their act together.
