Hi,
I am very much interested to do the job. I am Wordpress developer with more than 15 years of professional experience. I can create a custom import plugin to import your required CSV consisting Teams and Competitions. Please share the csv file so I can take a look.
I am quite sure that you'll be fully satisfied by the project. I expect a postive response from you and want to make long term relation with you.
If you have any questions then please contact me so we can discuss.
Thanks,
Hammad
