As I started with the work in this week, I would able to complete the entire work within the next week. But I will be ready to give demo in the next Wednesday.

Since I started with work this week, I would be able to complete the entire work within the next week. Although I will be ready to give demo the next Wednesday.

How do the above two sentences differ by using 'as' and 'since'?
Also correct the grammar mistakes.

'Since' is similar to 'because' or 'although'.
Using 'as' means describing it as it is happening.

'As' shouldn't be used for future tense as it describes somethings that has happened or is happening.

The first sentence has the wrong tense.
The second sentence has been corrected in a few places.
Starting a sentence with a 'but' in this type of context doesn't sound good.

I can understand it better if you explain why it is incorrect.
