Website Graphic/illustration designer

I need an illustrator that can create several images for my startup website, the following is required:

1x Main header image - this can be anything that is reflective of the overall business, i.e: customers using wifi in a mixture of the businesses that we service (barber shop, coffee shop etc).

3x small images reflective of topic (plug it in, wait 5 minutes , connected)

4x large images reflective of topic (Connect, Collect, Build & Engage)

More information on each section can be found on the wireframe I have put together below.

The Startup Business:
We provide a small plug & play box that plugs into existing wifi routers, it then enables buisnesses (cafes, barbers, coffee shops, hotels, restaurants), this then allows the business owner to capture customer data, build profiles & send marketing emails to their customers.


Information:
I have created a wireframe of the website and it can be found at the following link.

Where there is a grey image is where I need to have a grapic created, the graphic should reflect the topic. Ignore the size on the current placeholder image, I have just used a placeholder and this is not reflective of the actual size.

Images must be unique & provided in PSD format.

To give an idea of the type of images I am looking for, for the 4x main images, here is a dribbble design:

for the main header, I would be looking for something like this, but shows a cafe, bar, barbershop & customers using wifi

To be very clear I am not looking to copy these examples, I am just giving an idea of the type of design I am looking for.
