Hello Fivetide,
It shows that you have a gr8 interest of registering domains but I am sure that domains might not be under your control/ownership

In future you will be registering more domains thus I will suggest you to check out for a hosting provider who can offer your a reseller account in which you get more free features like free reseller registrar account which can really help you to register your domains and be them under your control.
Also, if you need to transfer your domain you can get them done. Let me know if you need any kind of assistance in this regards, I am here
Also, you can host those domains and can start your business with the same provider.
Please let me know if you need my assistance, I will be at your disposal
Thank you.
