Dear Sir,
I am confident that I can finish this job in 2 days, at the most. I can provide you with the .gif files that you asked fore, and in addition I could also make an animated Flash movie for you.
I am new to getafreelancer, but I have some experience on rentacoder.com.
Accept my bid and you won't regret it.
Looking forward to hear from you
Mihai Popa
