I am also new to selling anything online but I have started posting things on Teachers Pay Teachers. Below is a link to my TpT site to a freebie that I spent some time on.
I really wanted something more hands on to do with my students with regards to where capitals go and where punctuation goes in a sentence. I created these using an idea I found in a book but altered it so it uses the First Hundred Fry words (which my kinders had to learn by the end of the year) to create short sentences. There are some mixed up words the kids can cut out and manipulate (if they can read it's also comprehension practice ;) The top has empty spaces where the kids can paste the words in order, then a space to re-write the sentence neatly, and another box to illustrate the sentence. My kinders loved it, but it can also be used for firsties. Well enjoy and if you like please comment (especially if you find any mistakes).
