If I may offer some advice:



You mentioned about working the shop by yourself for the first 6-7 months and concentrating on technique and marketing.



During that time you are not going to have time to work on technique and marketing.



You need to develope your marketing material and work on your techingue now.



Do not wait until you have no customers to work on your marketing. Then you will start to undercut your prices just to get work in the door.



I wish you the best of luck.
