For Example, larger company tends to offer you great service with bigger amount of fee because they spent a lot of money on advertisement to get new customers, but you can actually acquire good result with high possibilities. On the other side, smaller company usually offers you less amount of money. However as it proceeds, if you ask them to do something more you might have to pay extra service fee.
