I visit your profile, it seems you have good course and experience in graphic design. however, the way you write represent it, needs to be improved.
I think its better you write more of your abilities for services you can provide, in overview. for example, I read your overview and in third line I understand you are experience in graphic design. you need to bring this in top.
You should give good test, related to your field, for example photoshop and/or illustrator
You should upload your portfolios, not necessary work done via this site, you can upload your previous work, or you can make some of good design and upload them.
I hope this helps you,
don't forget to get back to me when you see results in couple of weeks.
Its simple, suppose you are going to purchase gold from any shop its cost high but if you want to sell same gold, you will get less amount. i mean to say they take processing charge. or imediator charge.
