Thank you for being here. Another post that I hope is easy?
Hello $10 milestone - do you have a Go Anywhere Server to test code?
Will give a 5 Star Review when this is done and will write such inspiring words for you, when done.

Please understand; there is hope you can give your “best” price; been unemployed, and have cancer with bills backing up, $10 possible? Please note $10 is the max total that I can handle for this (doing hourly reduces % fee). Will leave a Glowing paragraph of feedback 5 stars : - )

My funds are low but will pay quick and leave 5 stars. Please give your best possible for your bid ? (something reasonable?) Please note there is hope we can mutually complete this task; we can leave each other nice comments and 5 stars for each? Look at feedback on my profile, feedback I left for many others. Here is the project:

SINCERELY WOULD BE NICE TO MEET YOU PLEASE

ANY THOUGHTS ? Please note project is due in two hours as this projects deadline, as this is needed if we can get some done - then we can talk about next steps and 5 stars and another job also. If this is a good one and we are "successful"; would need a couple others setup, but will handle one at a time? Can you do this for something reasonable in a couple hours? thoughts ?
