For SaaS companies short term profitability always happens the expense of growth. Mediocre growth means no VC money, ever. It's really that simple.
However, if you run your SaaS shop well you'll still make bucket-loads of money, and it doesn't take much capital to get there. Raising 600k from angels shouldn't be a problem (easier in the US than in EU) if you have a good deck. You won't get a 600k bank loan if your business has no assets that can be liquidated during bankruptcy. The downside of creating a medium-growth but profitable company is that you'll have to run it for the better part of a decade and you're unlikely to sell the company for more than 3x revenue at the end. You also won't be able to hire the best people if you're not a high growth company (no stock options, no CV prestige, less intellectually challenging work).
If you want to shoot for the moon forget about bank loans or profitability. Raise money (angel or series A, depending on where you're at), hire like crazy, grow like crazy, and so on. Failure is likely, and the stress will cost you.
I've seen too many people mess up by trying to do something in between a high-octane startup and a lifestyle business. You've got to choose one, and it looks like you've not come to terms with this yet.
