Help with outside projects

[callmeD]

Three years ago I built my home on the lake, and am only now getting to the outside landscaping projects. I am looking for someone to help with the following:

(1) Landscaping and bringing in a couple of large boulders to compliment what is already there

(2) Leveling an area and building stairs with railroad ties or other non-permanent materials

(3) Designing a parking area in the front of my cottage with some natural material. I want to soften that look with shrubs and perennials surrounding the parking area.

I need ideas of what will work best for the location, keeping in mind I want all of this to be designed "naturally" and to blend in with the wooded feel to the location and lake, and, of course, low maintenance!

Do I need different contractors or does anyone do all three?

Thanks for any suggestions you have.
