I am looking for a designer for landing pages for my company

I am looking to work with a designer to create a number of landing pages for our law firms.

I am seeking landing pages not the full websites for our companies namely;

1. West London legal centre (we need a landing page to cover all of west london)
2. North London legal service (we need a landing page to cover all of north london)
3. Landing page in Mayfair central london for central london solicitors

We are looking for low cost designers and if reliable will then offer more work in web development.
