The consulting / building combo is a good way to keep earning moderately well while trying to build a new co.

Building revenue generation is not easy. If you're going all-in on the build, there may well come a point where if your revenues are not sufficient you will start to feel pain. If you can structure the development process to deliver revenue from as simple and maintainable a product as possible and quickly find a route to sales that would be ideal.

I would guess that in terms of surviving to long term viability there are far more not-so-great but quickly revenue-generating products than there are great products that were unfortunately slow to get recognised and generate revenue. With cash, further development is possible to clean a product up - without it, even great stuff will rot. There are tons of genius ideas that have been through successful (working) development but then just died because they never made money.

Access sales resource - effective sales resource (not easy to find) - as quickly as possible. If you're aiming for investment financing, remember that few things build investor confidence like existing sales and cash flow.
