3 short explainer animations (combined total 3 mins)

I need a simple but professional 2d animated explainer video to describe a software product. It needs to be broken into three parts; an overview (1.5 mins) and a two bolt ons (45secs).

I'm looking for someone who is creative that can visually showcase what the software does
I will provide a professional voiceover
It should be have a contemporary feel and carry a cheerful tone

I'm looking for someone who has created many explainer animations before that can show me examples of their work to hopefully find something that is aligned to what I am looking for.

There is not a massive budget available for this project so please only bid if you can complete this work to a high standard within a reasonable timeframe.

Looking forward to receiving your examples and bids.
