BREACH OF CONTRACT FOR FENCING

March 26th 2017, we hired Nick Billman to enclose our patio, April 18th, build 2 sheds, May 23rd, add circle to our drive, and April 28th, remove and replace our fence with a pipe fence.
Each job had a contract w/bid and date of completion. Also contract had warranties of 5 yrs for patio and sheds, then 10yrs on fence.
The roof on the patio leaked with first rain. I called Nick and he came out to fix it the next day and said if it leaks again to let him know. Afterwards we have had leaks every time it rained. I called him and he said he would take care of it. As of today, 9-16-17, he still hasn't come out to do that.
The sheds Nick built are good and he did a good job on the circle drive.
However the fence is not completed. Nick requested weekly checks towards the labor cost to pay his workers. Against my husband's better judgement, he agreed to pay him weekly, although the contract stated 30%down and balance on completion.
June 15th was last check my husband paid NIck. We paid him total price of contract except for $100.00 and was looking forward to completion of fence shortly thereafter.
That was the last time we saw Nick. Most of the pipe posts are cemented in but the top rail and fencing is not done. He never came back to finish the job. I have called, emailed, and texted him to please finish this fence and Nick hasn't answered and told me when he's going to complete the fence. The last email I sent on 9/7, I asked him to reimburse me for labor to finish the fence and we would hire someone else. He still hasn't answered me.
So here we are, out over $12,000.00 and no fence. Now we have to someone else to finish Nicks job. We are senior citizens and on a fixed income, this sure hurts.
My husband is 76 and a military vet. It's a shame that we were taken advantage of in such a way. I don't know how he sleeps at night.
