Please: -->Don’t Bid if you didn’t understand the project and you do not have a similar experience or something to show. Priority to freelance who has done something similar. -->DON’T Put the placeholder amount (will be ignored), go through it understand the project and then provide the quote. We assume whatever you have put in your quote or bid for the task. Must be done within deadline. Preference to those who can complete it as soon as possible. Include how many do you need, and we need the task done by the deadline. -->Please also consider out budget range before bidding. We are confident that it should cost more than that based on the experience of a freelancer. Please, discuss all your conditions, limitation, requirements etc. before the start of the project or the agreement. But please have some idea before putting the bid amount(not to waste your and my time, putting one amount and quoting much higher later). The requirement list is exclusive. If you have any questions or need clarification, please ask before you apply. However, I may only respond to one who is interested in (I feel they can do it).
