Hello
I can write the 4 articles, pointing out interesting aspects of the topics and underling a problem or two that people can encounter, then offering a solution that would come out of acces to an online service that would make their respective problems easier, or solvable... would you like that idea?
if I can choose, i would choose Project Management, Human Resources, Time Sheets and Inventory, but I can work on any of the topics
I can start as soon as you place the milestone and finish in 1-2 days
I know freelancer will place us in a top, but the first possitions are offered by earning, not other criteria. you can check the online samples, and you can see the tests taken (for me it's US Eng lvl 3, the highest one, in this case)
thanks and let me know if you are interested
