sounds ok for me (30$ milestone for first script 20$ for second and your word about feedback vote, opinion and recommend)....with one exception - i need to be 100% you can do the job
therefore I i suggest like this : I award you the project, you make the script to work for 1 country, Czech Republic - as I am in CZ so I can test the script - if everything is OK, than I make the milestone of $30
