I have 5 years of experience working with GameMaker Studio. You can find a few tutorials written by myself in the community, as well as a number of game assets on the GameMaker Marketplace. Due to some time limitations, I am restricted to taking on smaller projects at this time. Feel free to contact me to discuss details - I will let you know if it will be possible to complete the assigned task within a timely manner. I am willing to discuss payment and find a price that will fit within your budget. Paid jobs are preferable, however I am willing to consider cost-share projects. If you are interested, please contact me at email@example.com.
