DNS and ssl and email domain problems

I am having some DNS, SSL, and email domain problems and I have barely attempted to troubleshoot them. I need some help fixing these issues so they can be resolved as quickly as possible. I am looking for a freelancer to help with this task and do not require them to provide a step-by-step report. I just need the problems fixed so that we can get back on track. Please let me know if you are available and have the expertise needed to complete this job. Thanks for your time.
