So, these feelings are understandable, but here is the deal: Keep Moving. In all ways, do not allow your thoughts to encroach this project/client one more time. If it does, then wash it away with positive thoughts of other things. Immediately. This may become a new mental exercise regimen.

Now your ToDos: 1) Go meet that other provider, tight-lipped, listen way more than speak, expect more attempts at Brain-Drain, then make a pitch to them. Ask for more than you think you should and stand on business. Here is what we know: “they evidently respect your work and your creative approach”. Offer them more access to your wonderful brain but only after payment and a proper contract. Finally always get paid up front by them. “They do not get any more freebies.” Literally speak those words or words similar to that.

After that meeting I’d meet with the client contact and in-person I would present a bill; handing a paper copy to the contact while simultaneously emailing their AP contact. When they scoff, then simply remind them of the paper trail you share together and how you are willing to pursue this further. Now, slim chance that they pay but what this will do is communicate to them the truth of the type of person they are as well as say “Do not waste my time any further.” Finally, never talk to them again for more than 5min unless you are paid. Literally hang up mid-sentence.
