@Donny Sales is precisely what I've been in need of for some time. The on going pain point for me is selling licenses to companies for a product and/or custom integrations (services) specifically to corporate. Navigating those deals and agreements is a major pain point. Connecting with buyers is harder.
My latest adventures have also taken me in a MRR direction with a lower price point targeting small businesses and individuals. This probably isn't as attractive to someone in sales. Far less opportunity for commission, etc. On the up-side, connecting with buyers directly is far easier.
However, both scenarios come with a lot of intricacies and an advisor for each (maybe it's a few advisors even who happen to specialize in x, y, or z) would be very helpful.
...And of course when you're talking about a startup (a bootstrapped one at that) cash isn't always available. Commission, small amounts of equity (again remember pre-funding), these become the only thing to barter with. At least until there is funding (raised or via sales). I do like things like Clairty.fm and such where you can pay by the minute/hour for advice too. Having a couple hundred here or there for some quality info and guidance is within I think most startup's budget.
As a consultant, I myself have had plenty of people paying me by the minute/hour in a similar fashion. It'd be great to simply have one big forum (or some format) to exchange knowledge and help, but I have yet to see that work. FounderDating is quite nice though.
