I've no doubt you will find a company who will roll your lawn. Many lawn service guys will give the customer what they want even when its wrong. It makes them more repeat business.
Its better to address the issues causing the unevenness. Rolling compacts the soil and causes further damage.
I recommend you talk to a competent turf expert who can asses your lawn and give you an analysis. A one time consultation should be free. Get at least two and compare what they recommend and what plan they offer. Then you may decide to do the corrective work yourself. It will likely take a season to get the lawn into shape.
Instead of rolling start by core aerating followed by a fertilizer application and crabgrass pre-emergent. Talk to the folks at The Anderson's about which products are best for your lawn and when to time the applications.
Slice back part of your turf to just below the roots and look for white grubs. If you've got 10 or more per square foot you have a grub problem. You can handle this two ways. Apply a curative grub application NOW. Cold weather has delayed the timing this year. There's about 5 or 6 days left if the soil warms as predicted by the weather forecast. Dylox is very good. There is a VERY short window in the early spring when a chemical grub application will work.
Or wait until late July/early August to apply a preventive grub control. Merit (imidacloprid) is recommended. Most lawn companies only do the late summer application because spring applications are exceptionally hard to time to be effective and they can't get around to all their customers in such a short period. If the lawn is really bad I do two applications the first year, spring and again in late July/early August then an annual late July/early August application thereafter.
Ohio State University Extension has numerous free factsheets about lawn care that will easily enable a homeowner to do a competent job of maintaining their lawn themselves or to be able to understand enough to weed out the competent from the "anything for a buck" lawn care company.
