Graphic designer needed for SaaS Corporate Website Design (no developing)

Current website: www.aptbacs.co.uk

About APT: APT LTD has created iConnect, cloud-based payments software for the processing of Direct Debit & Direct Credit in the UK.
Every day thousands of businesses rely on BACS payments providers to pay their suppliers and employee salaries or collect subscription fees. Direct credit and direct debit are the main ways to execute these payments.

In conclusion, we are a finance technology company specializing in payments. We are looking for a very clean corporate and professional look. We are providing you with a template and brand guidelines/colors and you would take the template and create relevant graphics (such as illustrations if that’s your creative solution or mockups or find relevant images of laptops or whatever you would decide to do) and wireframe for the following pages.
As template already gives you lots of premade material, we expect deliverables to be concentrated on custom made graphics/illustrations and colour matched sections and clear/clean user experience.

We would need 1 option for both desktop and mobile versions (8 desktop pages, 8 mobile pages)

So far, we are not changing the text or structure, just looking to refresh the design.
