I'm not a founder, but the exact same problem comes up at large companies as well. Get it done quickly or get it done fast, get it done right or get it done as well as you know how to.
It really comes down to how much you're going to gain out of this solution, how long it's supposed to (or will) stay in place, and what it will cost you to do it right. Cost is not only a function of time and real dollars, but also opportunity cost that you could have been doing something else.
You may not have to worry about something that doesn't look great representing you. How often is it seen? Internal? Quick and dirty, it's probably going to change in the future anyhow. Do the people seeing it care that much? For example, an admin interface (unless it's part of the reasons you buy) may not have to look good, just get the job done. Only 1-2 users in a company would see that, and the rest see the other interface. You have time to make it better later.
