One thing I've learnt is that there is always room for negotiation. Call the other business owner and come up with a time-frame to rebrand your company. Get him to agree with that time-frame and move on. That way you could use the remaining cash for a customer push and replenish your cash reserve at the same time. Prepare your rebranding peacefully and if you actually run out of cash, you won't have to rebrand (in some countries, this is costly). Another thing: contact the domain squatter of the other brand. Ask him how much he wants for the domain. If you run out of Cash, consider selling your domain to the other business owner for half the price. Heck, you could even sell your website and design.
