After speaking with my accountant I need two small things to proceed with the deal:

1. We need a valuation certificate.

We need a good in depth analysis made by experts but not an automated free service. Without it we both can't be sure in the price.

2. We need a trademark verification as well. Just a formality to be sure you have no problems with trademarks.

Good companies offers this as a part of appraisal. I asked in the forum about reliable valuation/TM verification services.

If the evaluation comes higher you can change your asking price. After you send me the professional evaluation via email (usually it takes one day to obtain it) we'll be doing business.
