Click the "get started now" button and let’s get started! (see above). Select a hosting plan that fits your needs. (Normally, if you are just starting out I recommend the basic plan but, if you are really serious about this and want more resources & power go with their Prime or Pro plan). Keep in mind, you can always upgrade your plan as you grow.
Your money is either in charge of you or you’re in charge of it, there’s no middle ground. Using some type of personal finance software can help alleviate some of that money stress and better allow you to manage your money effectively. Without it, you may just be setting yourself up for constant financial worry. Life is already tough enough and there’s no need to make it more difficult by simply hoping your money issues will all work out in your favor. Hint: they won’t.
And while you’re at it -- don’t create an additional public, “professional” profile associated with your business. For example, I already have a personal profile on Facebook that I largely keep private; the practice I’m talking about would be if I created a second, public one under the name “AmandaZW HubSpot,” or something along those lines. People usually do that to connect with professional contacts on Facebook, without letting them see personal photos or other posts. But the fact of the matter is that creating more than one personal account goes against Facebook's terms of service.
