i need advice on my dog "training" please share if you have any Jumping barking  

I have an 18 month chow/ golden mix that i have had for about a month now.. when we got him he didnt know how to sit, laydown, fetch or give paw... My husband taught him all that in the first weekend we had him! However our biggest issues are teaching him to NOT jump up on everyone he sees and NOT to bark at everyone and everydog that comes into his sight... My husband is trying , and none of the methods seem to work, ive done some research online, but doesnt seem to be getting anywhere with those either... My daughter is getting really discouraged, she doesnt even want to walk him anymore because he seems to be out of control... i know paatience is a key factor with dogs, but people are starting to not even visit anymore because they dont want to be barbrred with dog when \they walk in the door... Plesae if you have any advice that would be greatly appreciated... Anything that worked OR didnt work for you?? Thanks in advance
