Dealing with contractor.

[Ilcar Rosario]

Hello guy's is my first time  dealing with contractor, i been reading a-lot post on biggerpokets and one of the post the person  recommend to ask the contractor for the contractor license number, insurance and bound information to make sure is legit. And my question is, you ask for thous information upfront before the bid or they give you thous information on the bid? i ask one of the contractor he said he will not give the insurance and the bound info. i would like to hear you guy's opinion thank you in advance.
