Search the List for Landscaper, or possibly handyman. There are also specialty retaining wall contractors if you google that term plus your town name, then check their names on AL for possible reviews.
A couple of suggestions - be sure to tie the ties together - typically with holes drilled down through and treated with ground-contact wood treatment, then drive 1/2" (minimal) or 3/4" rebar down through and into the ground to hold together as a unit, though some prefer to spike a 2x4 of treated wood to the back face every couple of feet which can work but will eventually let loose unless lag bolted. Also, if you tilt the wall back into the slope about 5-10%, it will look a lot better - for two reasons. First, almost all retaining walls, and certainly all gravity type like ties, willl tilt forward bit by bit due to frost action or just vibration and settling - any little movement forward lets rocks and dirt drop in behind it so it cannot tilt back towards the slope, but progressibely gets wedged forward bit by bit. Second reason - a uniform thickness retaining wall that is vertical gives an opptical illusion that it is actually tipping forward a couple of %, so a 10% layback avoids that both when installed and after it tilts a bit forward. A stepped or terraced wall commonly looks better than flush-faced, unless you are space limited like along a driveway. Also more stable. Also can avoid the issue that nay retaining wall oer 4' high has to be designed by an engineer to get building permit. Google this search phrase for design possibilities - images of railroad tie retaining walls If you live in California or Oregon or other eco-crazy state, check regs first - creosoted ties are being banned for landscaping use in several states, even though the release of creosol is extremely minimal after a treated timber or poles is a couple of year old.
