Internet upgrade GI

I am looking for a freelancer to help me with an internet upgrade for my business. My current internet speed is average and I am looking for a data service upgrade that will allow me to use up to 100 GB of data. I need someone who is experienced working with internet infrastructure and networks to efficiently and quickly complete the upgrade. If you have experience in this area, please let me know so I can get the job done in a timely manner. Thank you for your time and for considering this project.
