請幫我修改以下的文法：

I am seeking for a position that will give me opportunities to utilize and develop my skills so that I can make contributions to the company and the community. I am now working at an entry-level position in a marketing firm which provides me with the chance to move up to higher positions and acquire more experience. I contribute to my present company by employing my all-round marketing experience and strategic technique to perform innovative marketing analysis and marketing management that uplifts the management of acquisition, retention and customer relations.
