Lampros In order the Andersson tactic to seem legit you must have on your site the amount you need and the amount gathered from donations so far..... otherwise it seems like a stunt....
for example how would the one donating will know that the amount was gathered ?? friends and family will be easy to learn such information but if you want help from people that do not know you i am sure they will need more info in order to trust you their money. Also will they know if the donations exeeded the amount needed (which in that case they should have their money back) ??
the way you are presenting it, it is not very credible. Especially since you ask for help from foreigners. And although in greece we know you are one of the most legit drivers around when it comes to sponsorship i think people from other countries will need more information than just "take your word for it".
