If you're sure you can get the business to support it, then go to the bank and get a loan. If you aren't able to do that, you're probably stuck slowly bootstrapping. (You're asking for advice, but it's hard to really help because you haven't given a lot of details.) If you have 20 customers after years and it's not profitable enough to hire more developers, I'm guessing you'll have a hard time finding investors. But I don't know. In all cases, I wish you luck and hope you find what it takes to get lift-off. I know how hard it is.

I looked at cofounderslab a while back. Can't remember what stopped me completing it then. It seems to have evolved a lot. Thanks for replying, much appreciated.

Edit: CoFoundersLab looks really hopeful David. It's just gone down for updates but I liked what I saw - thanks again!
