Snow removal - rates/recommendations (and possibly lawn/landscaping come spring)

Hi all, Due to some mobility issues, I've become "that guy" and fell behind on getting the latest batch of snows fully cleared. And, there seems to be more on the way. Looking for an idea of what general rates are like for a sidewalk (L-shaped, corner lot) and a walkway/steps, to shovel and salt, if anyone is willing to give a ballpark. As this may be ongoing, I'm likely looking for recs on a company that does snow, as well as lawn/landscaping once it gets warm again. But, with caveats...I don't keep much cash on hand, and I don't have Paypal, Venmo, etc. So this would need to be a company that can do a secure card payment. Appreciate any feedback, good or bad. Thanks, Keith
