I can't speak to RI specifically, but most states allow a buyer's remorse grace for 3 days if the agreement was transacted in your home.
Even if you are on the hook so-to-speak, it does not mean you can't cancel the job but they may be able to get damages if they can prove them. For example, if they already purchased materials specifc for this job that they cannot use elsewhere; if they turned down anoher job to accommodate your project, etc.
You may want to first test the water and simply inform them that you will not be moving forward and see what type of response you get. Some upstanding providers would rather walk away then get caught up in a dispute and all the bad wrap that comes with it. But you know others will make s big stink and threaten to sue.
You may want to consult a local civil litigator if you feel this cannot be resolved amicably.

Notify the contractor by phone that you want to cancel. See what his answer is ask him if he has purchased any materials already on your behalf. If he claims he has, ask to see the invoices. Thank him for his time in estimating the work. Immediately follow up with a letter cancelling the contract. You might be liable for damages but since no work has started, unlikely that he would have much in the nature of provable damages beyond the deposit you already paid. If he gets nasty, advise him that you felt pressured to sign and upon reflection do not want to do business that way. Trust me, if he pressured you to sign the contract, it is likely that he will "find" other items that require fixing and pressure you into signing further change orders for work that you likely do not need to have done. Cut your losses now while you still can.
