Hi,
I've read your project. You need someone to collect facebook pages and groups, their membership size and URL, right? This is very easy job. I have done similar project.
If you want I can do a sample work for you before selection. If you like my work, you can select me.
Please let me know, do you have any restriction in case of membership size?
And What kind of groups and pages you are looking for?
My budget is $30 for 400 data.(complete and accurate).
And I will finish this job within 24 hours. After your 100% satisfaction you will pay me.
Waiting for your response.
Thanks
Regards
