I'm a Level 2 Seller, but still $100 are way too much without detailed info. Or some guarantee.
Dear sir, apologies but the price tag is fixed at $100 and will remain so. The reason, as mentioned earlier in OP, is that you could use it to your advantage to rapidly reach the top in search results. More importantly, it will help new users who are truly struggling to even see their gigs appear in search results. In my career as coach, you cannot imagine how many clients asked me why their gigs would not appear in search results despite being published. You are already a Level 2 seller, thus I personally believe this guide is not for you; but rather for those in hope of reaching your level and rank and trust. Thank you for your interest.
