Hello Joanne, while some landlords may hesitate to rent to section 8 tenants, others might be thrilled. I would recommend asking a Realtor to search for properties that fit your needs and then the agent can find out whether it is an option before showing whether it would be a problem. I briefly had a client with a similar situation last year. (That wasn't you, was it?)
While it may be challenging, nothing is impossible. Although the reference given below by Stephanie is a great start. If I may be of any help, please feel free to contact me at (786) 277-8425.
Best of luck to you and your family.
