What you get with this Hourlie
Well, if you show me a sketch or drawing, and list your requirements then I can tell you how many hours of my time you need. Then you can buy however many hourlies you need to complete the job.
What the Seller needs to start the work
I need a very clear idea of what you want, because I'm really not much good at mind-reading.
So, make your information clear enough that if you show it to your window cleaner or car mechanic, they will understand exactly what you are after. In which case, I will understand too!
If you are not sure what information is needed, just ask me. I am very friendly, and usually do not bite.
