I need some logos similar to these for a lead gen website

I'm looking for logos that are modeled after a professional style and in a suggested color palette. I need between 2 and 4 variations and/or revisions of the logo. I have a specific lead gen website that needs to have a logo that accurately reflects its purpose, but hasn't been seen before. I require high quality, modern designs so I'm looking for someone who is experienced and experienced in creating the right logo.
