Custom Rubber Stamp Idea

So I  have been asked a few times if I do custom stamps.  Someone asked if I could put their name or business name,  a cute image and the words "Thank You" on a stamp.  Also even to  put handmade with love with there name and  a cute little graphic.  So I have been doing some thinking this morning and what if I offered a few different templates where you can customize the words, and put your favorite 2 Cute image!    I could see the Cat-Knit image with Hand knitted with love by Heidi, maybe a couple small hearts?  Or maybe the turtle sundae image with the words "thank you"  and then your name, business name or email?  
Let's see you can write what ever you wanted but here are some templates I could have
1. Handmade with love by (with 2 cute image) 
      a. Handmade by
2. Knitted with love by (with 2 cute image) 
      a. Crocheted with love by
3. Baked with love by (with 2 cute image)
4. Planted with love by (with 2 cute image)
5.  Just your name, child's name etc (with 2 cute image)
6. Address stamps (with 2 cute image)
     a. just Your name or your Family name
7. 2 cute image with "Thank You", name and phone number?


That is what I have thought of so far!


Here are the estimate prices:
1.  They would be wood mounted and can very in size 
   a. 1 x 1 -$10.00 plus shipping
   b. 1.5 x 1 - $16.00 plus shipping
   c.  1.5 x 1.5  -$20.00 plus shipping
   d.  2 x 2 - 25.00 plus shipping (Maybe able to offer Free Shipping on 2x2?)


I believe from the time you place an order then I design the stamp put correct info
and then I would like to send your a jpeg email for approval, spelling?
About a week and a half to 2 week turn around.


Just an idea, since I was asked earlier this week I thought I would look into the prices and such.  Please let me know what you think of Custom stamps or if you have any other Ideas!
