Hi Buyer!
I like your project, and I'm much interested in it.
I'll take this challenge! You said not to bid more than $50, but here is the deal; If all your requirements, as mentioned in your project details, are fulfilled to your satisfaction, reasonably, pay me $150. If not, pay $30 and close the project as 'well-completed'. No one is hurt!
So, what do you say to this proposal?
