Yes, you should definitely do it if you're looking for professionalism in your terms and conditions page. However, if you think you're capable of handling it yourself then do your best and work on it. If you have even a slightest doubt then don't do it yourself, or spoil everything by trying; instead just hire a professional and let them handle it. You can look for such professionals on any freelancer sites such as fiverr, elance, and so on. The best thing is that you could always check their work samples before having to be paid. That way you could determine which works suit you well and which do not. It saves a lot of time and money. So, best of luck and have a nice day, and keep up your good work.
