TEAM HERE, experienced in web search, ready to start.
Sir, I have requested for 7 days, thinking that we may not find images with transparent background for a number of logos, in such cases we may need to retouch them using Photo editor.
I estimate there are around 100-150 airline companies in total in the target wiki pages you mentioned.
It would be our best try to complete the project as urgent, but for a successful completion I expect your cordial understanding and consideration. To make our clients satisfied is the first priority, but sometimes things make us take time to proper completion of projects.
If I was able to convince you on the point rightly, I hope we can have a long term sustainable working relationship :-)
Ask me questions, if any.
Sincere regards,
Jubair
