just start it,,, dont be scarry, just do it,,, and u ll find the best way u r...... maybe u need to buy some cages,, and nameplate, and dont forget to buy the pet ! so the another important one is a partner,, you must have a partner in this job.. or you will be bored because of you work alone,, and for making the website,, I dont know yet to make it
You start and as business grows you will get the requisite experience.
