Design agency needs brand illustrations for website

We need illustrations for the hero of several pages on our website. The illustrations will be for the following pages:

1. Home page
2. Web Design services
3. SEO services
4. Digital Advertising

We want to achieve a unique illustration that looks contemporary. As a design agency we need this to look very professional

Here you can take a look at the home page design we have with a stock illustration:

This was the best stock image we could find but it is not really what were looking for. We think that using the colors less sparingly and using black lines more might look good but we are open to all ideas.

As for the objects in the illustrations, we don’t like the use of gears and wrenches to convey web development so we would like the artist’s input on how to achieve something less cliche

Objects/Subjects: (possible but not necessary)
We do like clouds
Our bird logo,
Our local lighthouse in New York https://www.lighthousefriends.com/huntington1.jpg

My priority here is for the front page, so if it helps to focus only on that initially I would be open to that

Ive included links to

1. Our current website - goodpep.com
2. Our in-progress new homepage design - http://spencerg7.sg-host.com/mocks/home.jpg
3. robinhood.com - If anyone can achieve this kind of illustration please let me know.
